A bot that posts messages to rooms when an email is received. Ideal for uses where a short message is desired in a chat room when a newsletter goes out.

Note: Some experience with MX records is ideal.

The bot runs best on port 25 to receive all incoming mail to your server. The bot does not (currently) send mail out, but does process all inbound emails to try and get them to the proper room (letting them disappear if no room can be mapped).

1. Set up an MX record to point to your domain. For example, email.example.com 10 vps3.example.com (email.example.com being the domain, 10 the priority, and vps3.example.com being the server's hostname)
2. Optionally install spamassassin and spamc: sudo apt-get install spamassassin spamc - be sure to enable them!
3. Install nodejs and npm (v18+ preferred).
4. Clone this repository and run yarn install.
5. Copy config/default.yaml to config/production.yaml and configure accordingly.
6. Set the environment variable NODE_ENV to production and run yarn start.
7. Start using your bot!

There is also a Docker image available at darkdecoy/matrix-email-bot - map your config to /app/config/production.yaml.

Some mailing lists require you to send an email in order to subscribe. This requires setting up a mailserver (such as postfix) in send-only mode because the bot is handling incoming mail. After setting up your mail server, use it to send an email to the list with the From address being the room you'd like to announce to. For example: echo "Subscribe" | mail -s "Subscribe" [email protected] -aFrom:[email protected]
