Go to Gmail and under Settings Accounts and Import Send mail as, click "Add another email address"
When prompted for "Name", enter the name that you want your email to be seen as "From" (e.g. "Linus Torvalds").
When prompted for "Email address", enter the full email address of an alias you created under My Account Domains Aliases (e.g. hello@example.com)
Uncheck "Treat as an alias"
Click "Next Step" to proceed
When prompted for "SMTP Server", enter smtp.forwardemail.net and change the port to 465
When prompted for "Username", enter the full email address of an alias you created under My Account Domains Aliases (e.g. hello@example.com)
When prompted for "Password", paste the password from Generate Password in step 3 above
Select the radio button for "Secured connection using SSL"

Click "Next Step" to proceed
When prompted for "SMTP Server", enter smtp.gmail.com and leave the port as 587
When prompted for "Username", enter the portion of your Gmail address without the gmail.com part (e.g. just "user" if my email is user@gmail.com)

Important: If the "Username" portion is autofilled, then you will need to change this to the username portion of your Gmail address instead.
When prompted for "Password", paste from your clipboard the password you generated in step 2 above
Leave the radio button checked for "Secured connection using TLS"
Click "Add Account" to proceed
Open a new tab to Gmail and wait for your verification email to arrive (you will receive a verification code that confirms you are the owner of the email address you are attempting to "Send Mail As")
Once it arrives, copy and paste the verification code at the prompt you received in the previous step

Question 20

Why am I not receiving my test emails?

Accepted Answer

If you're sending a test email to yourself, then it may not show up in your inbox because it has the same "Message-ID" header.

This is a widely known issue, and also affects services such as Gmail. Here is the official Gmail answer regarding this issue.

If you continue to have issues, then it is most likely to be an issue with DNS propagation. You will need to wait a bit longer and try again (or try setting a lower TTL value on your TXT records).

Still having issues? Please contact us so we can help investigate the issue and find a quick resolution.

Question 21

How do I configure my email client to work with Forward Email?

Accepted Answer

Our service works with popular email clients such as:

Your username is your alias' email address and password is from Generate Password ("Normal Password").

Tip: If you are using Thunderbird, then ensure "Connection security" is set to "SSL/TLS" and Authentication method is set to "Normal password".

Type Hostname Protocol Ports IMAP imap.forwardemail.net SSL/TLS Preferred 993 and 2993 SMTP smtp.forwardemail.net SSL/TLS Recommended 465 and 2465 for SSL/TLS (recommended) or 587, 2587, 2525, and 25 for STARTTLS

Question 22

Why are my emails landing in Spam and Junk and how can I check my domain reputation?

Accepted Answer

This section guides you if your outbound mail is using our SMTP servers (e.g. smtp.forwardemail.net) (or forwarded via mx1.forwardemail.net or mx2.forwardemail.net) and it is being delivered in the Spam or Junk folder of recipients.

We routinely monitor our IP addresses against all reputable DNS denylists, therefore it is most likely a domain-reputation specific issue.

Emails can land in spam folders for several reasons:

Missing Authentication: Set up SPF, DKIM, and DMARC records.
Domain Reputation: New domains often have neutral reputation until they establish a sending history.
Content Triggers: Certain words or phrases can trigger spam filters.
Sending Patterns: Sudden increases in email volume can look suspicious.

You can try to use one or more of these tools to check your domain's reputation and categorization:

Tip

Start with a low volume of high-quality emails to build a positive reputation before sending in larger volumes.

Important

If your domain is on a blacklist, each blacklist has its own removal process. Check their websites for instructions.

Tip

If you need additional help or find that we are false-positive listed as spam by a certain email service provider, then please contact us.

Question 23

What should I do if I receive spam emails?

Accepted Answer

You should unsubscribe from the emailing list (if possible) and block the sender.

Please do not report the message as spam, but instead forward it to our manually curated and privacy-focused abuse prevention system.

The email address to forward spam to is: abuse@forwardemail.net

Question 24

Why are my test emails sent to myself in Gmail showing as "suspicious"?

Accepted Answer

If you see this error message in Gmail when you send a test to yourself, or when a person you're emailing with your alias sees an email from you for the first time, then please do not worry – as this is a built-in safety feature of Gmail.

You can simply click "Looks safe". For example, if you were to send a test message using the send mail as feature (to someone else), then they will not see this message.

However if they do see this message, it's because they were normally used to seeing your emails come from john@gmail.com instead of john@customdomain.com (just an example). Gmail will alert the users just to make sure things are safe just in case, there is no workaround.

Question 25

Can I remove the via forwardemail dot net in Gmail?

Accepted Answer

This topic is related to a widely known issue in Gmail where extra info appears next to a sender's name.

As of May 2023 we support sending email with SMTP as an add-on for all paid users – which means that you can remove the via forwardemail dot net in Gmail.

Note that this FAQ topic is specific for those using the How to Send Mail As using Gmail feature.

Please see the section on Do you support sending email with SMTP for configuration instructions.

Apple Mail MBOX https://support.apple.com/guide/mail/import-or-export-mailboxes-mlhlp1030/mac#apd37a3190755974 Fastmail EML https://www.fastmail.help/hc/en-us/articles/360060590573-Download-all-your-data#downloadmail Proton Mail MBOX/EML https://proton.me/support/export-emails-import-export-app Tutanota EML https://github.com/crepererum-oss/tatutanatata Gandi EML https://docs.gandi.net/en/gandimail/common_operations/backup_email.html#contents Zoho EML https://www.zoho.com/mail/help/import-export-emails.html#alink2 Other Use Thunderbird Set up your existing email account in Thunderbird and then use the ImportExportTools NG plugin to export and import your email. You may also be able to simply copy/paste or drag/drop emails between one account to another.
Download, install, and open Thunderbird.
Create a new account using your alias' full email address (e.g. you@yourdomain.com) and your generated password. If you do not yet have a generated password, then refer to our setup instructions.
Download and install the ImportExportTools NG Thunderbird plugin.
Create a new local folder in Thunderbird, and then right click on it → select the ImportExportTools NG option → choose Import mbox file (for MBOX export format) – or – Import messages / Import all messages from a directory (for EML export format).
Drag/drop from the local folder to a new (or existing) IMAP folder in Thunderbird you wish to upload messages to in IMAP storage with our service. This will ensure they are backed up online with our SQLite encrypted storage.

Tip: If you are confused as to how to import into Thunderbird, then you can refer to official instructions at https://kb.mozillazine.org/Importing_folders and https://github.com/thunderbird/import-export-tools-ng/wiki.

Important: Once you have completed the export and import process, then you may also want to enable forwarding on your existing email account and set up an auto-responder to notify senders that you have a new email address (e.g. if you were previously using Gmail and are now using an email with your custom domain name).

Congratulations! You've successfully completed all steps.

Question 29

How do I use my own S3-compatible storage for backups?

Accepted Answer

Paid plan users can configure their own S3-compatible storage provider on a per-domain basis for IMAP/SQLite backups. This means your encrypted mailbox backups can be stored on your own infrastructure instead of (or in addition to) our default storage.

Supported providers include Amazon S3, Cloudflare R2, MinIO, Backblaze B2, DigitalOcean Spaces, and any other S3-compatible service.

Setup

Create a private bucket with your S3-compatible provider. The bucket must not be publicly accessible.
Create access credentials (access key ID and secret access key) with read/write permissions to the bucket.
Go to My Account Domains Advanced Settings Custom S3-Compatible Storage.
Check "Enable custom S3-compatible storage" and fill in your endpoint URL, access key ID, secret access key, region, and bucket name.
Click "Test Connection" to verify your credentials, bucket access, and write permissions.
Click "Save" to apply the settings.

How Backups Work

Backups are triggered automatically for every connected IMAP alias. The IMAP server checks all active connections once per hour and dispatches a backup for each connected alias. A Redis-based lock prevents duplicate backups from running within 30 minutes of each other, and the actual backup is skipped if a successful backup was already completed within the last 24 hours (unless the backup was explicitly requested by a user for download).

Backups can also be triggered manually by clicking "Download Backup" for any alias in the dashboard. Manual backups always run regardless of the 24-hour window.

The backup process works as follows:

The SQLite database is copied using VACUUM INTO, which creates a consistent snapshot without interrupting active connections and preserves the database encryption.
The backup file is verified by opening it to confirm encryption is still valid.
A SHA-256 hash is computed and compared against the existing backup in storage. If the hash matches, the upload is skipped (no changes since last backup).
The backup is uploaded to S3 using multipart upload via the @aws-sdk/lib-storage library.
A signed download URL (valid for 4 hours) is generated and emailed to the user.

Backup Formats

Three backup formats are supported:

Format Extension Description sqlite .sqlite Raw encrypted SQLite database snapshot (default for automatic IMAP backups) mbox .zip Password-protected ZIP containing mailbox in mbox format eml .zip Password-protected ZIP containing individual .eml files per message

Tip: If you have .sqlite backup files and want to convert them to .eml files locally, use our standalone CLI tool convert-sqlite-to-eml. It works on Windows, Linux, and macOS and does not require a network connection.

File Naming and Key Structure

When using custom S3 storage, backup files are stored with an ISO 8601 timestamp prefix so that each backup is preserved as a separate object. This gives you a full backup history in your own bucket.

The key format is:

{ISO 8601 timestamp}-{alias_id}.{extension}

For example:

2025-03-01T12:00:00.000Z-65a31c53c36b75ed685f3fda.sqlite 2025-03-01T12:00:00.000Z-65a31c53c36b75ed685f3fda.zip 2025-03-02T12:00:00.000Z-65a31c53c36b75ed685f3fda.sqlite

The alias_id is the MongoDB ObjectId of the alias. You can find it in the alias settings page or via the API.

When using the default (system) storage, the key is flat (e.g. 65a31c53c36b75ed685f3fda.sqlite) and each backup overwrites the previous one.

Note: Since custom S3 storage retains all backup versions, storage usage will grow over time. We recommend configuring lifecycle rules on your bucket to automatically expire old backups (e.g. delete objects older than 30 or 90 days).

Data Ownership and Deletion Policy

Your custom S3 bucket is entirely under your control. We never delete or modify files in your custom S3 bucket — not when an alias is deleted, not when a domain is removed, and not during any cleanup operations. We only write new backup files to your bucket.

This means:

Alias deletion — When you delete an alias, we remove the backup from our default system storage only. Any backups previously written to your custom S3 bucket remain untouched.
Domain removal — Removing a domain does not affect files in your custom bucket.
Retention management — You are responsible for managing storage in your own bucket, including configuring lifecycle rules to expire old backups.

If you disable custom S3 storage or switch back to our default storage, existing files in your bucket are preserved. Future backups will simply be written to our default storage instead.

Security

Your access key ID and secret access key are encrypted at rest using AES-256-GCM before being stored in our database. They are only decrypted at runtime when performing backup operations.
We automatically validate that your bucket is not publicly accessible. If a public bucket is detected, the configuration will be rejected on save. If public access is detected at backup time, we fall back to our default storage and notify all domain administrators by email.
Credentials are validated on save via a HeadBucket call to ensure the bucket exists and credentials are correct. If validation fails, custom S3 storage is automatically disabled.
Each backup file includes a SHA-256 hash in its S3 metadata, which is used to detect unchanged databases and skip redundant uploads.

Error Notifications

If a backup fails when using your custom S3 storage (e.g. due to expired credentials or a connectivity issue), all domain administrators will be notified by email. These notifications are rate-limited to once every 6 hours to prevent duplicate alerts. If your bucket is detected as publicly accessible at backup time, administrators will be notified once daily.

API

You can also configure custom S3 storage via the API:

curl -X PUT https://api.forwardemail.net/v1/domains/example.com \ -u API_TOKEN: \ -d has_custom_s3=true \ -d s3_endpoint=https://s3.us-east-1.amazonaws.com \ -d s3_access_key_id=YOUR_ACCESS_KEY_ID \ -d s3_secret_access_key=YOUR_SECRET_ACCESS_KEY \ -d s3_region=us-east-1 \ -d s3_bucket=my-email-backups

To test the connection via the API:

curl -X POST https://api.forwardemail.net/v1/domains/example.com/test-s3-connection \ -u API_TOKEN:

Question 30

How do I convert SQLite backups to EML files?

Accepted Answer

If you download or store SQLite backups (either from our default storage or your own custom S3 bucket), you can convert them to standard .eml files using our standalone CLI tool convert-sqlite-to-eml. EML files can be opened with any email client (Thunderbird, Outlook, Apple Mail, etc.) or imported into other mail servers.

Installation

You can either download a pre-built binary (no Node.js required) or run it directly with Node.js:

Pre-built binaries — Download the latest release for your platform from GitHub Releases:

Platform Architecture File Linux x64 convert-sqlite-to-eml-linux-x64 Linux arm64 convert-sqlite-to-eml-linux-arm64 macOS Apple Silicon convert-sqlite-to-eml-darwin-arm64 Windows x64 convert-sqlite-to-eml-win-x64.exe

macOS users: After downloading, you may need to remove the quarantine attribute before running the binary:

sudo xattr -rd com.apple.quarantine ./convert-sqlite-to-eml-darwin-arm64

(Replace ./convert-sqlite-to-eml-darwin-arm64 with the actual path to the downloaded file.)

Linux users: After downloading, you may need to make the binary executable:

chmod +x ./convert-sqlite-to-eml-linux-x64

(Replace ./convert-sqlite-to-eml-linux-x64 with the actual path to the downloaded file.)

From source (requires Node.js >= 18):

cd tools/convert-sqlite-to-eml npm install node index.js

Usage

The tool supports both interactive and non-interactive modes.

Interactive mode — run without arguments and you will be prompted for all inputs:

./convert-sqlite-to-eml Forward Email - Convert SQLite Backup to EML ============================================= Path to SQLite backup file: /path/to/backup.sqlite IMAP/alias password: ******** Output ZIP path [/path/to/backup-2025-03-01T12-00-00-000Z.zip]:

Non-interactive mode — pass arguments via command-line flags for scripting and automation:

./convert-sqlite-to-eml \ --path /path/to/backup.sqlite \ --password "your-imap-password" \ --output /path/to/output.zip Flag Description --path Path to the encrypted SQLite backup file --password IMAP/alias password for decryption --output Output path for the ZIP file (default: auto-generated with ISO 8601 timestamp) --help Show help message

Output Format

The tool produces a password-protected ZIP archive (AES-256 encrypted) containing:

README.txt INBOX/ .eml .eml Sent/ .eml Drafts/ .eml

EML files are organized by mailbox folder. The ZIP password is the same as your IMAP/alias password. Each .eml file is a standard RFC 5322 email message with full headers, body text, and attachments reconstructed from the SQLite database.

How It Works

Question 31

Do you support self-hosting?

Accepted Answer

Yes, as of March 2025, we support a self-hosted option. Read the blog here. Checkout the self-hosted guide to get started. And for those interested in a more broken down step-by-step version see our Ubuntu or Debian based guides.

Question 32

How do I get started and set up email forwarding?

Accepted Answer

Estimated Setup Time: Less than 10 minutes

Getting Started: Carefully read and follow steps one through eight listed below. Be sure to replace the email address of user@gmail.com with the email address you want to forward emails to (if it isn't already accurate). Similarly be sure to replace example.com with your custom domain name (if it isn't already accurate).

If you have already registered your domain name somewhere, then you must completely skip this step and go to step two! Otherwise you can click here to register your domain name.
Do you remember where you registered your domain? Once you remember this, then follow the instructions below:
Important: You must open a new tab and sign in to your domain registrar. You can easily click on your "Registrar" below to automatically do this. In this new tab, you must navigate to the DNS management page at your registrar – and we have provided the step by step navigation steps below under the "Steps to Configure" column. Once you've navigated to this page in the new tab, you can return to this tab and proceed to step three below. Do not close the opened tab yet; you will need it for future steps!

Important: Don't see your registrar name listed here? Simply search on the Internet for "how to change DNS records on $REGISTRAR" (replacing $REGISTRAR with the name of your registrar – e.g. "how to change DNS records on GoDaddy" if you're using GoDaddy).
Using your registrar's DNS management page (the other tab you have opened), set the following "MX" records:
Important: Note that there should be NO other MX records set. Both records shown below MUST exist. Be sure there are no typos; and you have both mx1 and mx2 spelled correctly. If there were already MX records that existed, please delete them completely. The "TTL" value does not need to be 3600, it could be a lower or higher value if necessary.
Name/Host/Alias TTL Type Priority Answer/Value "@", ".", or blank 3600 MX 0 mx1.forwardemail.net "@", ".", or blank 3600 MX 0 mx2.forwardemail.net
Using your registrar's DNS management page (the other tab you have opened), set the following TXT record(s):
Important: If you are on a paid plan, then you must completely skip this step and go to step five! If you are not on a paid plan, then your forwarded addresses will be publicly searchable – go to My Account Domains and upgrade your domain to a paid plan if desired. If you would like to learn more about paid plans see our Pricing page. Otherwise you can continue to choose one or more combinations from Option A to Option F listed below.

Option A: If you are forwarding all emails from your domain, (e.g. "all@example.com", "hello@example.com", etc) to a specific address "user@gmail.com":
Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=user@gmail.com
Tip: Make sure to replace the values above in the "Value" column with your own email address. The "TTL" value does not need to be 3600, it could be a lower or higher value if necessary. A lower time to live ("TTL") value will ensure any future changes made to your DNS records are propagated throughout the Internet quicker – think of this as how long it will be cached in-memory (in seconds). You can learn more about TTL on Wikipedia.

Option B: If you just need to forward a single email address (e.g. hello@example.com to user@gmail.com; this will also forward "hello+test@example.com" to "user+test@gmail.com" automatically):
Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=hello:user@gmail.com
Option C: If you are forwarding multiple emails, then you'll want to separate them with a comma:
Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=hello:user@gmail.com,support:user@gmail.com
Option D: You can have an infinite amount of forwarding emails setup – just make sure to not wrap over 255 characters in a single-line and start each line with "forward-email=". An example is provided below:
Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=hello:user@gmail.com,support:user@gmail.com "@", ".", or blank 3600 TXT forward-email=help:user@gmail.com,foo:user@gmail.com "@", ".", or blank 3600 TXT forward-email=orders:user@gmail.com,baz:user@gmail.com "@", ".", or blank 3600 TXT forward-email=info:user@gmail.com,beep:user@gmail.com "@", ".", or blank 3600 TXT forward-email=errors:user@gmail.com,boop:user@gmail.com
Option E: You can also specify a domain name in your TXT record to have global alias forwarding (e.g. "user@example.com" will get forwarded to "user@example.net"):
Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=example.net
Option F: You can even use webhooks as a global or individual alias to forward emails to. See the example and full section on webhooks titled Do you support webhooks below.
Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=alias:https://requestbin.com/r/en8pfhdgcculn
Option G: You can even use regular expressions ("regex") for matching aliases and for handling substitutions to forward emails to. See the examples and full section on regex titled Do you support regular expressions or regex below.

Need advanced regex with substitution? See the examples and full section on regex titled Do you support regular expressions or regex below.

Simple Example: If I want all emails that go to `linus@example.com` or `torvalds@example.com` to forward to `user@gmail.com`:
Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=/^(linus|torvalds)$/:user@gmail.com
Important: Catch-all forwarding rules could also be described as "fall-through". This means that incoming emails which match at least one specific forwarding rule will be used instead of the catch-all. Specific rules include email addresses and regular expressions.

For example:
forward-email=hello:first@gmail.com,second@gmail.com
Emails sent to hello@example.com will **not** be forwarded to second@gmail.com (catch-all) with this configuration, and instead only be delivered to first@gmail.com.
Using your registrar's DNS management page (the other tab you have opened), additionally set the following TXT record: Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT v=spf1 a include:spf.forwardemail.net -all
Important: If you are using Gmail (e.g. Send Mail As) or G Suite, then you'll need to append include:_spf.google.com to the value above, for example:

v=spf1 a include:spf.forwardemail.net include:_spf.google.com -all

Tip: If you already have a similar line with "v=spf1", then you'll need to append include:spf.forwardemail.net right before any existing "include:host.com" records and before the "-all" in the same line, for example:

v=spf1 a include:spf.forwardemail.net include:host.com -all

Note that there is a difference between "-all" and "~all". The "-" indicates that the SPF check should FAIL if it does not match, and "~" indicates that the SPF check should SOFTFAIL. We recommend to use the "-all" approach to prevent domain forgery.

You may also need to include the SPF record for whichever host you are sending mail from (e.g. Outlook).
Verify your DNS records using our "Verify Records" tool available at My Account Domains Setup.
Send a test email to confirm it works. Note that it might take some time for your DNS records to propagate.
Tip: If you are not receiving test emails, or receive a test email that says "Be careful with this message", then see the answers for Why am I not receiving my test emails and Why are my test emails sent to myself in Gmail showing as "suspicious" respectively.
If you wish to "Send Mail As" from Gmail, then you will need to watch this video, or follow the steps under How to Send Mail As Using Gmail below.

Congratulations! You've successfully completed all steps.

Tip: Optional add-ons are listed below. Note that these add-ons are completely optional and may not be necessary. We wanted to at least provide you with additional information if necessary.

Optional Add-on: If you're using the How to Send Mail As using Gmail feature, then you may want to add yourself to an allowlist. See these instructions by Gmail on this topic.

Question 33

Can I use multiple MX exchanges and servers for advanced forwarding?

Accepted Answer

Yes, but you should only have one MX exchange listed in your DNS records.

Do not attempt to use "Priority" as a way to configure multiple MX exchanges.

Instead, you need to configure your existing MX exchange to forward mail for all non-matching aliases to our service's exchanges (mx1.forwardemail.net and/or mx2.forwardemail.net).

If you are using Google Workspace and you want to forward all non-matching aliases to our service, then see https://support.google.com/a/answer/6297084.

If you are using Microsoft 365 (Outlook) and you want to forward all non-matching aliases to our service, then see https://learn.microsoft.com/en-us/exchange/mail-flow-best-practices/use-connectors-to-configure-mail-flow/set-up-connectors-to-route-mail and https://learn.microsoft.com/en-us/exchange/mail-flow-best-practices/manage-mail-flow-for-multiple-locations.

Question 34

How do I set up a vacation responder (out of office auto-responder)?

Accepted Answer

Go to My Account Domains Aliases and either create or edit the alias you would like to configure a vacation autoresponder for.

You have the ability to configure a start date, end date, subject, and message, and enable or disable it at anytime:

Plaintext subject and message are currently supported (we use striptags package internally to remove any HTML).
Subject is limited to 100 characters.
Message is limited to 1000 characters.
Setup requires Outbound SMTP configuration (e.g. you will need to setup DKIM, DMARC, and Return-Path DNS records).
- Go to My Account Domains Settings Outbound SMTP Configuration and follow setup instructions.
Vacation responder cannot be enabled on global vanity domain names (e.g. disposable addresses are not supported).
Vacation responder cannot be enabled for aliases with wildcard/catch-all (*) nor regular expressions.

Unlike mail systems such as postfix (e.g. that use the sieve vacation filter extension) – Forward Email automatically adds your DKIM signature, dummy-proofs connection issues when sending vacation responses (e.g. due to common SSL/TLS connection issues and legacy maintained servers), and even supports Open WKD and PGP encryption for vacation responses.

We only send once per allowlisted sender every 4 days (which is similar to Gmail's behavior).
- Our Redis cache uses a fingerprint of alias_id and sender, whereas alias_id is the alias MongoDB ID and sender is either the From address (if allowlisted) or root domain in the From address (if not allowlisted). For simplicity the expiry of this fingerprint in cache is set to 4 days.
- Our approach of using the root domain parsed in the From address for non-allowlisted senders prevents abuse from relatively unknown senders (e.g. malicious actors) from flooding vacation responder messages.
We only send when the MAIL FROM and/or From is not blank and does not contain (case-insensitive) a postmaster username (the portion before the @ in an email).
We don't send if the original message had any of the following headers (case-insensitive):
- Header of auto-submitted with a value not equal to no.
- Header of x-auto-response-suppress with a value of dr, autoreply, auto-reply, auto_reply, or all
- Header of list-id, list-subscribe, list-unsubscribe, list-help, list-post, list-owner, list-archive, x-autoreply, x-autorespond, or x-auto-respond (regardless of value).
- Header of precedence with a value of bulk, autoreply, auto-reply, auto_reply, or list.
We don't send if the MAIL FROM or From email address ends with +donotreply, -donotreply, +noreply, or -noreply.
We don't send if the From email address username portion was mdaemon and it had a case-insensitive header of X-MDDSN-Message.
We don't send if there was a case-insensitive content-type header of multipart/report.

Question 35

How do I set up SPF for Forward Email?

Accepted Answer

Using your registrar's DNS management page, set the following TXT record:

Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT v=spf1 a include:spf.forwardemail.net -all

Important: If you are using Gmail (e.g. Send Mail As) or G Suite, then you'll need to append include:_spf.google.com to the value above, for example:

v=spf1 a include:spf.forwardemail.net include:_spf.google.com -all

Important: If you are using Microsoft Outlook or Live.com, you'll need to append include:spf.protection.outlook.com to your SPF TXT record, for example:

v=spf1 a include:spf.forwardemail.net include:spf.protection.outlook.com -all

Tip: If you already have a similar line with "v=spf1", then you'll need to append include:spf.forwardemail.net right before any existing "include:host.com" records and before the "-all" in the same line, for example:

v=spf1 a include:spf.forwardemail.net include:host.com -all

Note that there is a difference between "-all" and "~all". The "-" indicates that the SPF check should FAIL if it does not match, and "~" indicates that the SPF check should SOFTFAIL. We recommend to use the "-all" approach to prevent domain forgery.

You may also need to include the SPF record for whichever host you are sending mail from (e.g. Outlook).

Question 36

How do I set up DKIM for Forward Email?

Accepted Answer

Go to My Account Domains Settings Outbound SMTP Configuration and follow setup instructions.

Question 37

How do I set up DMARC for Forward Email?

Accepted Answer

Go to My Account Domains Settings Outbound SMTP Configuration and follow setup instructions.

Question 38

How do I view DMARC Reports?

Accepted Answer

Forward Email provides a comprehensive DMARC Reports dashboard that allows you to monitor your email authentication performance across all your domains from a single interface.

What are DMARC Reports?

DMARC (Domain-based Message Authentication, Reporting, and Conformance) reports are XML files sent by receiving mail servers that tell you how your emails are being authenticated. These reports help you understand:

How many emails are being sent from your domain
Whether those emails are passing SPF and DKIM authentication
What actions receiving servers are taking (accept, quarantine, or reject)
Which IP addresses are sending email on behalf of your domain

How to Access DMARC Reports

Go to My Account DMARC Reports to view your dashboard. You can also access domain-specific reports from My Account Domains by clicking the "DMARC" button next to any domain.

Dashboard Features

The DMARC Reports dashboard provides:

Summary Metrics: Total reports received, total messages analyzed, SPF alignment rate, DKIM alignment rate, and overall pass rate
Messages Over Time Chart: Visual trend of email volume and authentication rates over the past 30 days
Alignment Summary: Donut chart showing SPF vs DKIM alignment distribution
Message Disposition: Stacked bar chart showing how receiving servers handled your emails (accepted, quarantined, or rejected)
Recent Reports Table: Detailed list of individual DMARC reports with filtering and pagination
Domain Filtering: Filter reports by specific domain when managing multiple domains

Why This Matters

For organizations managing multiple domains (like enterprises, non-profits, or agencies), DMARC reports are essential for:

Identifying unauthorized senders: Detect if someone is spoofing your domain
Improving deliverability: Ensure your legitimate emails pass authentication
Monitoring email infrastructure: Track which services and IPs are sending on your behalf
Compliance: Maintain visibility into email authentication for security audits

Unlike other services that require separate DMARC monitoring tools, Forward Email includes DMARC report processing and visualization as part of your account at no additional cost.

Requirements

DMARC Reports are available for paid plans only
Your domain must have DMARC configured (see How do I set up DMARC for Forward Email)
Reports are automatically collected when receiving mail servers send them to your configured DMARC reporting address

Weekly Email Reports

Paid plan users automatically receive weekly DMARC report summaries via email. These emails include:

Summary statistics for all your domains
SPF and DKIM alignment rates
Message disposition breakdown (accepted, quarantined, rejected)
Top reporting organizations (Google, Microsoft, Yahoo, etc.)
IP addresses with alignment issues that may need attention
Direct links to your DMARC Reports dashboard

Weekly reports are sent automatically and cannot be disabled separately from other email notifications.

Question 39

How do I connect and configure my contacts?

Accepted Answer

To configure your contacts, use the CardDAV URL of: https://carddav.forwardemail.net (or simply carddav.forwardemail.net if your client allows it)

Question 40

How do I connect and configure my calendars?

Accepted Answer

To configure your calendar, use the CalDAV URL of: https://caldav.forwardemail.net (or simply caldav.forwardemail.net if your client allows it)

Question 41

How do I add more calendars and manage existing calendars?

Accepted Answer

If you'd like to add additional calendars, then just add a new calendar URL of: https://caldav.forwardemail.net/dav/principals/calendar-name (be sure to replace calendar-name with your desired calendar name)

You can change a calendar's name and color after creation – just use your preferred calendar application (e.g. Apple Mail or Thunderbird).

Question 42

How do I connect and configure tasks and reminders?

Accepted Answer

To configure tasks and reminders, use the same CalDAV URL as calendars: https://caldav.forwardemail.net (or simply caldav.forwardemail.net if your client allows it)

Tasks and reminders will automatically be separated from calendar events into their own "Reminders" or "Tasks" calendar collection.

Setup instructions by platform:

macOS/iOS:

Add a new CalDAV account in System Preferences > Internet Accounts (or Settings > Accounts on iOS)
Use caldav.forwardemail.net as the server
Enter your Forward Email alias and generated password
After setup, you'll see both "Calendar" and "Reminders" collections
Use the Reminders app to create and manage tasks

Android with Tasks.org:

Install Tasks.org from Google Play Store or F-Droid
Go to Settings > Synchronization > Add Account > CalDAV
Enter server: https://caldav.forwardemail.net
Enter your Forward Email alias and generated password
Tasks.org will automatically discover your task calendars

Thunderbird:

Install the Lightning add-on if not already installed
Create a new calendar with type "CalDAV"
Use URL: https://caldav.forwardemail.net
Enter your Forward Email credentials
Both events and tasks will be available in the calendar interface

Question 43

Why can't I create tasks in macOS Reminders?

Accepted Answer

If you're having trouble creating tasks in macOS Reminders, try these troubleshooting steps:

Check account setup: Ensure your CalDAV account is properly configured with caldav.forwardemail.net
Verify separate calendars: You should see both "Calendar" and "Reminders" in your account. If you only see "Calendar", the task support may not be fully activated yet.
Refresh account: Try removing and re-adding your CalDAV account in System Preferences > Internet Accounts
Check server connectivity: Test that you can access https://caldav.forwardemail.net in your browser
Verify credentials: Ensure you're using the correct alias email and generated password (not your account password)
Force sync: In Reminders app, try creating a task and then manually refreshing the sync

Common issues:

"Reminders calendar not found": The server may need a moment to create the Reminders collection on first access
Tasks not syncing: Check that both devices are using the same CalDAV account credentials
Mixed content: Ensure tasks are being created in the "Reminders" calendar, not the general "Calendar"

Question 44

How do I set up Tasks.org on Android?

Accepted Answer

Tasks.org is a popular open-source task manager that works excellently with Forward Email's CalDAV task support.

Installation and Setup:

Install Tasks.org:
- From Google Play Store: Tasks.org
- From F-Droid: Tasks.org on F-Droid
Configure CalDAV sync:
- Open Tasks.org
- Go to ☰ Menu > Settings > Synchronization

Enter Forward Email settings:
- Server URL: https://caldav.forwardemail.net
- Username: Your Forward Email alias (e.g., you@yourdomain.com)
- Password: Your alias-specific generated password
- Tap "Add Account"
Account discovery:
- Tasks.org will automatically discover your task calendars
- You should see your "Reminders" collection appear
- Tap "Subscribe" to enable sync for the task calendar
Test sync:
- Create a test task in Tasks.org
- Check that it appears in other CalDAV clients (like macOS Reminders)
- Verify changes sync both ways

Features available:

✅ Task creation and editing
✅ Due dates and reminders
✅ Task completion and status
✅ Priority levels
✅ Subtasks and task hierarchy
✅ Tags and categories
✅ Two-way sync with other CalDAV clients

Troubleshooting:

If no task calendars appear, try manually refreshing in Tasks.org settings
Ensure you have at least one task created on the server (you can create one in macOS Reminders first)
Check network connectivity to caldav.forwardemail.net

Question 45

How do I set up SRS for Forward Email?

Accepted Answer

We automatically configure Sender Rewriting Scheme ("SRS") – you do not need to do this yourself.

Question 46

Question 52

Do you support calendars (CalDAV)?

Accepted Answer

Yes, as of February 5, 2024 we have added this feature. Our server is caldav.forwardemail.net and is also monitored on our status page.

It supports both IPv4 and IPv6 and is available over port 443 (HTTPS).

Login Example Description Username user@example.com Email address of an alias that exists for the domain at My Account Domains. Password ************************ Alias-specific generated password.

In order to use calendar support, the user must be the email address of an alias that exists for the domain at My Account Domains – and the password must be an alias-specific generated password.

Question 53

Do you support tasks and reminders (CalDAV VTODO)?

Accepted Answer

Yes, as of October 14, 2025 we have added CalDAV VTODO support for tasks and reminders. This uses the same server as our calendar support: caldav.forwardemail.net.

Our CalDAV server supports both calendar events (VEVENT) and tasks (VTODO) components using unified calendars. This means each calendar can contain both events and tasks, providing maximum flexibility and compatibility across all CalDAV clients.

How calendars and lists work:

Each calendar supports both events and tasks - You can add events, tasks, or both to any calendar
Apple Reminders lists - Each list you create in Apple Reminders becomes a separate calendar on the server
Multiple calendars - You can create as many calendars as you need, each with its own name, color, and organization
Cross-client sync - Tasks and events sync seamlessly between all compatible clients

Supported task clients:

Task features supported:

Task creation, editing, and deletion
Due dates and start dates
Task completion status (NEEDS-ACTION, IN-PROCESS, COMPLETED, CANCELLED)
Task priority levels
Recurring tasks
Task descriptions and notes
Multi-device synchronization
Subtasks with RELATED-TO property
Task reminders with VALARM

The login credentials are the same as for calendar support:

Login Example Description Username user@example.com Email address of an alias that exists for the domain at My Account Domains. Password ************************ Alias-specific generated password.

Important notes:

Each Reminders list is a separate calendar - When you create a new list in Apple Reminders, it creates a new calendar on the CalDAV server
Thunderbird users - You'll need to manually subscribe to each calendar/list you want to sync, or use the calendar home URL: https://caldav.forwardemail.net/dav/your-email@domain.com/
Apple users - Calendar discovery happens automatically, so all your calendars and lists will appear in Calendar.app and Reminders.app
Unified calendars - All calendars support both events and tasks, giving you flexibility in how you organize your data

Question 54

Do you support contacts (CardDAV)?

Accepted Answer

Yes, as of June 12, 2025 we have added this feature. Our server is carddav.forwardemail.net and is also monitored on our status page.

It supports both IPv4 and IPv6 and is available over port 443 (HTTPS).

Login Example Description Username user@example.com Email address of an alias that exists for the domain at My Account Domains. Password ************************ Alias-specific generated password.

In order to use contacts support, the user must be the email address of an alias that exists for the domain at My Account Domains – and the password must be an alias-specific generated password.

Question 55

Do you support sending email with SMTP?

Accepted Answer

Yes, as of May 2023 we support sending email with SMTP as an add-on for all paid users.

Important: Please ensure you have read our Terms, Privacy Policy, and Outbound SMTP Limits – your use is considered acknowledgement and agreement.

Important: If you are using Gmail, then refer to our Send Mail As with Gmail guide. If you are a developer, then refer to our email API docs.

When prompted for SMTP server name, enter smtp.forwardemail.net
When prompted for SMTP server port, enter 465 (SSL/TLS) – see alternate SMTP ports if necessary

Tip: If you are using Thunderbird, then ensure "Connection security" is set to "SSL/TLS" and Authentication method is set to "Normal password".
When prompted for SMTP server password, paste the password from Generate Password in step 3 above
Save your settings and send your first test email – if you are having issues, then please contact us

Important: Please note that in order to maintain IP reputation and ensure deliverability, we have a manual review process on a per-domain basis for outbound SMTP approval. This typically takes less than 24 hours, with most requests being honored within 1-2 hours. In the near future we aim to make this process instant with additional spam controls and alerting. This process ensures that your emails reach the inbox and your messages don't get marked as spam.

Question 56

Do you support OpenPGP/MIME, end-to-end encryption ("E2EE"), and Web Key Directory ("WKD")?

Accepted Answer

Yes, we support OpenPGP, end-to-end encryption ("E2EE"), and the discovery of public keys using Web Key Directory ("WKD"). You can configure OpenPGP using keys.openpgp.org or self-host your own keys (refer to this gist for WKD server setup).

WKD lookups are cached for 1 hour to ensure timely email delivery → therefore if you add, change, or remove your WKD key, then please email us at support@forwardemail.net with your email address in order for us to manually purge the cache.
We support PGP encryption for messages that are forwarded via WKD lookup or using an uploaded PGP key on our interface.
Uploaded keys take prevalance as long as the PGP checkbox is enabled/checked.
Messages sent to webhooks are not currently encrypted with PGP.
If you have multiple aliases that match for a given forwarding address (e.g. regex/wildcard/exact combo) and if more than one of these contains an uploaded PGP key and has PGP checked → then we will send you an error alert email and will not encrypt the message with your uploaded PGP key. This is very rare and usually only applies to advanced users with complex alias rules.
PGP encryption will not be applied to email forwarding through our MX servers if the sender had a DMARC policy of reject. If you require PGP encryption on all mail then we suggest to use our IMAP service and configure your PGP key for your alias for inbound mail.

You can validate your Web Key Directory setup at https://wkd.chimbosonic.com/ (open-source) or https://www.webkeydirectory.com/ (proprietary).

Automatic Encryption: If you are using our outbound SMTP service and sending unencrypted messages, then we will automatically attempt to encrypt messages on a per-recipient basis using Web Key Directory ("WKD").

Important: You must follow all of the following steps in order to enable OpenPGP for your custom domain name.

Download and install your email client's recommended plugin below:
Email Client Platform Recommended Plugin Notes Thunderbird Desktop Configure OpenPGP in Thunderbird Thunderbird has built-in support for OpenPGP.

Tip: You can visit https://keys.openpgp.org/manage to manage your key in the future.

Optional Add-on: If you are using our encrypted storage (IMAP/POP3) service and want all email stored in your (already encrypted) SQLite database to be encrypted with your public key, then go to My Account Domains Aliases (e.g. hello@example.com) Edit OpenPGP and upload your public key.
Add a new CNAME record to your domain name (e.g. example.com):
Name/Host/Alias TTL Type Answer/Value openpgpkey 3600 CNAME wkd.keys.openpgp.org
Tip: If your alias is using our vanity/disposable domains (e.g. hideaddress.net), then you can skip this step.

Congratulations! You've successfully completed all steps.

Question 57

Do you support S/MIME encryption?

Accepted Answer

Yes, we support S/MIME (Secure/Multipurpose Internet Mail Extensions) encryption as defined in RFC 8551. S/MIME provides end-to-end encryption using X.509 certificates, which is widely supported by enterprise email clients.

We support both RSA and ECC (Elliptic Curve Cryptography) certificates:

RSA certificates: 2048-bit minimum, 4096-bit recommended
ECC certificates: P-256, P-384, and P-521 NIST curves

To configure S/MIME encryption for your alias:

Obtain an S/MIME certificate from a trusted Certificate Authority (CA) or generate a self-signed certificate for testing.

Tip: Free S/MIME certificates are available from providers like Actalis or Actalis Free S/MIME.
Export your certificate in PEM format (the public certificate only, not the private key).
Go to My Account Domains Aliases (e.g. hello@example.com) Edit S/MIME and upload your public certificate.
Once configured, all incoming emails to your alias will be encrypted using your S/MIME certificate before being stored or forwarded.

Note: S/MIME encryption is applied to incoming messages that are not already encrypted. If a message is already encrypted with OpenPGP or S/MIME, it will not be re-encrypted.

Important: S/MIME encryption will not be applied to email forwarding through our MX servers if the sender had a DMARC policy of reject. If you require S/MIME encryption on all mail then we suggest to use our IMAP service and configure your S/MIME certificate for your alias for inbound mail.

The following email clients have built-in S/MIME support:

Email Client Platform Notes Apple Mail macOS Built-in S/MIME support. Go to Mail > Preferences > Accounts > your account > Trust to configure certificates. Apple Mail iOS Built-in S/MIME support. Go to Settings > Mail > Accounts > your account > Advanced > S/MIME to configure. Microsoft Outlook Windows Built-in S/MIME support. Go to File > Options > Trust Center > Trust Center Settings > Email Security to configure. Microsoft Outlook macOS Built-in S/MIME support. Go to Tools > Accounts > Advanced > Security to configure. Thunderbird Desktop Built-in S/MIME support. Go to Account Settings > End-To-End Encryption > S/MIME to configure. GNOME Evolution Desktop Built-in S/MIME support. Go to Edit > Preferences > Mail Accounts > your account > Security to configure. KMail Desktop Built-in S/MIME support. Go to Settings > Configure KMail > Identities > your identity > Cryptography to configure.

Congratulations! You've successfully configured S/MIME encryption for your alias.

Question 58

Do you support Sieve email filtering?

Accepted Answer

Yes! We support Sieve email filtering as defined in RFC 5228. Sieve is a powerful, standardized scripting language for server-side email filtering that allows you to automatically organize, filter, and respond to incoming messages.

Supported Sieve Extensions

We support a comprehensive set of Sieve extensions:

Extension RFC Description fileinto RFC 5228 File messages into specific folders reject / ereject RFC 5429 Reject messages with an error vacation RFC 5230 Automatic vacation/out-of-office replies vacation-seconds RFC 6131 Fine-grained vacation response intervals imap4flags RFC 5232 Set IMAP flags (\Seen, \Flagged, etc.) envelope RFC 5228 Test envelope sender/recipient body RFC 5173 Test message body content variables RFC 5229 Store and use variables in scripts relational RFC 5231 Relational comparisons (greater than, less than) comparator-i;ascii-numeric RFC 4790 Numeric comparisons copy RFC 3894 Copy messages while redirecting editheader RFC 5293 Add or delete message headers date RFC 5260 Test date/time values index RFC 5260 Access specific header occurrences regex draft-ietf-sieve-regex Regular expression matching enotify RFC 5435 Send notifications (e.g., mailto:) environment RFC 5183 Access environment information mailbox RFC 5490 Test mailbox existence, create mailboxes special-use RFC 8579 File into special-use mailboxes (\Junk, \Trash) duplicate RFC 7352 Detect duplicate messages ihave RFC 5463 Test for extension availability subaddress RFC 5233 Access user+detail address parts

Extensions Not Supported

The following extensions are not currently supported:

Extension Reason include Security risk (script injection) and requires global script storage mboxmetadata / servermetadata Requires IMAP METADATA extension support foreverypart / mime / extracttext / replace / enclose Complex MIME tree manipulation not yet implemented

Example Sieve Scripts

File newsletters into a folder:

require ["fileinto"]; if header :contains "List-Id" "newsletter" { fileinto "Newsletters"; }

Auto-reply when on vacation:

require ["vacation"]; vacation :days 7 :subject "Out of Office" "I am currently out of the office and will respond when I return.";

Mark messages from important senders:

require ["imap4flags"]; if address :is "from" "boss@example.com" { setflag "\Flagged"; }

Reject spam with specific subjects:

require ["reject"]; if header :contains "subject" ["lottery", "winner", "urgent transfer"] { reject "Message rejected due to spam content."; }

Managing Sieve Scripts

You can manage your Sieve scripts in several ways:

Note: Sieve filtering is applied to incoming messages before they are stored in your mailbox. Scripts are executed in order of priority, and the first matching action determines how the message is handled.

Security: For security, redirect actions are limited to 10 per script and 100 per day. Vacation responses are rate-limited to prevent abuse.

Yes, as of August 14, 2024 we have added this feature. You can now go to My Account → Domains → Settings → Bounce Webhook URL and configure an http:// or https:// URL that we will send a POST request to whenever outbound SMTP emails bounce.

This is useful for you to manage and monitor your outbound SMTP – and can be used to maintain subscribers, opt-out, and detect whenever bounces occur.

Bounce webhook payloads are sent as a JSON with these properties:

email_id (String) - email ID that corresponds to an email in My Account → Emails (outbound SMTP)
list_id (String) - the List-ID header (case-insensitive) value, if any, from the original outbound email
list_unsubscribe (String) - the List-Unsubscribe header (case-insensitive) value, if any, from the original outbound email
feedback_id (String) - the Feedback-ID header (case-insensitive) value, if any, from the original outbound email
recipient (String) - the email address of the recipient that bounced or errored
message (String) - a detailed error message for the bounce
response (String) - the SMTP response message
response_code (Number) - the parsed SMTP response code
truth_source (String) - if the response code was from a trusted source, this value will be populated with the root domain name (e.g. google.com or yahoo.com)
bounce (Object) - an object containing the following properties that detail the bounce and rejection status
- action (String) - bounce action (e.g. "reject")
- message (String) - bounce reason (e.g. "Message Sender Blocked By Receiving Server")
- category (String) - bounce category (e.g. "block")
- code (Number) - bounce status code (e.g. 554)
- status (String) - bounce code from response message (e.g. 5.7.1)
- line (Number) - parsed line number, if any, from Zone-MTA bounce parse list (e.g. 526)
headers (Object) - key value pair of headers for the outbound email
bounced_at (String) - ISO 8601 formatted Date for when the bounce error occurred

For example:

{ "email_id": "66bcce793ef7b2a0928e14ba", "recipient": "example@gmail.com", "message": "The email account that you tried to reach is over quota.", "response": "552 5.2.2 The email account that you tried to reach is over quota.", "response_code": 552, "truth_source": "google.com", "bounce": { "action": "reject", "message": "Gmail Mailbox is full", "category": "capacity", "code": 552, "status": "5.2.2", "line": 300 }, "headers": {}, "bounced_at": "2024-08-24T01:50:02.828Z" }

Here are a few additional notes regarding bounce webhooks:

Question 63

Do you support webhooks?

Accepted Answer

Tip: Looking for documentation on bounce webhooks? See Do you support bounce webhooks? for more insight.

Yes, as of May 15, 2020 we have added this feature. You can simply add webhook(s) exactly like you would with any recipient! Please ensure that you have the "http" or "https" protocol prefixed in the webhook's URL.

Enhanced Privacy Protection: If you are on a paid plan (which features enhanced privacy protection), then please go to My Account Domains and click on "Aliases" next to your domain to configure your webhooks. If you would like to learn more about paid plans see our Pricing page. Otherwise you can continue to follow the instructions below.

If you are on the free plan, then simply add a new DNS TXT record as shown below:

For example, if I want all emails that go to alias@example.com to forward to a new request bin test endpoint:

Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=alias:https://requestbin.com/r/en8pfhdgcculn

Or perhaps you want all emails that go to example.com to forward to this endpoint:

Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=https://requestbin.com/r/en8pfhdgcculn

Here are additional notes regarding webhooks:

Question 64

Do you support regular expressions or regex?

Accepted Answer

Yes, as of September 27, 2021 we have added this feature. You can simply write regular expressions ("regex") for matching aliases and performing substitions.

Regular expression supported aliases are ones that start with a / and end with / and their recipients are email addresses or webhooks. The recipients can also include regex substitution support (e.g. $1, $2).

We support two regular expression flags including i and g. The case-insensitive flag of i is a permanent default and it is always enforced. The global flag of g can be added by you by affixing the ending / with /g.

Note that we also support our disabled alias feature for the recipient portion with our regex support.

Regular expressions are not supported on global vanity domains (as this could be a security vulnerability).

Enhanced Privacy Protection: If you are on a paid plan (which features enhanced privacy protection), then please go to My Account Domains and click on "Aliases" next to your domain to configure aliases, including those with regular expressions. If you would like to learn more about paid plans see our Pricing page.

Examples for Enhanced Privacy Protection

Alias Name Effect Test /^(linus|torvalds)$/ Emails to `linus@example.com` or `torvalds@example.com` (view test on RegExr) /^24highst(reet)$/ Emails to `24highst@example.com` or `24highstreet@example.com` (view test on RegExr)

Tip: To test these at RegExr, write the expression in the top box, and then type an example alias in the text box below. If it matches, it will turn blue.

Examples for the free plan

If you are on the free plan, then simply add a new DNS TXT record using one or more of the provided examples below:

Simple Example: If I want all emails that go to `linus@example.com` or `torvalds@example.com` to forward to `user@gmail.com`:

Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=/^(linus|torvalds)$/:user@gmail.com

Firstname Lastname Substitution Example: Imagine all of your company email addresses are of the `firstname.lastname@example.com` pattern. If I want all emails that go to the pattern of `firstname.lastname@example.com` to forward to `firstname.lastname@company.com` with substitution support (view test on RegExr):

Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=/^([A-Za-z]+)+\.([A-Za-z]+)+$/:$1.$2@company.com

Plus Symbol Filtering Substitution Example: If I want all emails that go to `info@example.com` or `support@example.com` to forward to `user+info@gmail.com` or `user+support@gmail.com` respectively (with substitution support) (view test on RegExr):

Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=/^(support|info)$/:user+$1@gmail.com

Webhook Querystring Substitution Example: Perhaps you want all emails that go to `example.com` to go to a webhook and have a dynamic querystring key of "to" with a value of the username portion of the email address (view test on RegExr):

Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=/^(.*?)$/:https://example.com/webhook?username=$1

Quiet reject example: If you want all emails that match a certain pattern to be disabled and quietly reject (appears to sender as if the message was sent successfully, but actually goes nowhere) with status code `250` (see Can I disable specific aliases), then simply use the same approach with a single exclamation mark "!". This indicates to the sender that the message was successfully delivered, but it actually went nowhere (e.g. blackhole or `/dev/null`).

Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=/^(linus|torvalds)$/:!

Soft reject example: If you want all emails that match a certain pattern to be disabled and soft reject with status code `421` (see Can I disable specific aliases), then simply use the same approach with a double exclamation mark "!!". This indicates to the sender to retry their email, and emails to this alias will be retried for approximately 5 days and then reject permanently.

Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=/^(linus|torvalds)$/:!!

Hard reject example: If you want all emails that match a certain pattern to be disabled and hard reject with status code `550` (see Can I disable specific aliases), then simply use the same approach with a triple exclamation mark "!!!". This indicates to the sender of a permanent error and emails will not retry, they will be rejected for this alias.

Name/Host/Alias TTL Type Answer/Value "@", ".", or blank 3600 TXT forward-email=/^(linus|torvalds)$/:!!!

Однако мы предоставили ссылки ниже для конвертации PST в формат MBOX/EML в зависимости от вашей операционной системы: Zinkuba для Windows (GitHub) readpst для Windows cygwin – (например, `readpst -u -o $OUT_DIR $IN_DIR`, заменяя `$OUT_DIR` и `$IN_DIR` на пути к выходной и входной директориям соответственно). readpst для Ubuntu/Linux – (например, `sudo apt-get install readpst`, а затем `readpst -u -o $OUT_DIR $IN_DIR`, заменяя `$OUT_DIR` и `$IN_DIR` на пути к выходной и входной директориям соответственно). readpst для macOS (через brew) – (например, `brew install libpst`, а затем `readpst -u -o $OUT_DIR $IN_DIR`, заменяя `$OUT_DIR` и `$IN_DIR` на пути к выходной и входной директориям соответственно).
