This page describes how to set this up. **Table of Contents** {{< toc >}} ## Requirements Handling incoming email messages requires an IMAP-enabled email account. The recommended strategy is to use [email sub-addressing](https://en.wikipedia.org/wiki/Email_address#Sub-addressing) but a catch-all mailbox does work too. The receiving email address contains a user/action specific token which tells Gitea which action should be performed. This token is expected in the `To` and `Delivered-To` header fields. Gitea tries to detect automatic responses to skip and the email server should be configured to reduce the incoming noise too (spam, newsletter). ## Configuration To activate the handling of incoming email messages you have to configure the `email.incoming` section in the configuration file. The `REPLY_TO_ADDRESS` contains the address an email client will respond to. This address needs to contain the `%{token}` placeholder which will be replaced with a token describing the user/action. This placeholder must only appear once in the address and must be in the user part of the address (before the `@`). An example using email sub-addressing may look like this: `incoming+%{token}@example.com` If a catch-all mailbox is used, the placeholder may be used anywhere in the user part of the address: `incoming+%{token}@example.com`, `incoming_%{token}@example.com`, `%{token}@example.com` ## Security Be careful when choosing the domain used for receiving incoming email. It's recommended receiving incoming email on a subdomain, such as `incoming.example.com` to prevent potential security problems with other services running on `example.com`.
