Hi, we have a plain vanilla Debian 12.9 server running that OS’s stable distribution of Dovecot. Has anyone here figured out how to **just add the [notifications.delta.chat](http://notifications.delta.chat) hookup** and not the other chatmail features we don’t want (like autoregistered acounts or filtering out of non-autocrypt messages)?

A good starting point is [https://delta.chat/en/help#instant-delivery](https://delta.chat/en/help#instant-delivery) for a high-level overview.

Chatmail servers don’t do much, they just store the push notification token of a user encrypted, and then send the encrypted token to [notifications.delta.chat](http://notifications.delta.chat), which forwards it to google/apple to trigger a push notification: [server/chatmaild/src/chatmaild/notifier.py at main · chatmail/server · GitHub](https://github.com/chatmail/server/blob/main/chatmaild/src/chatmaild/notifier.py)

A process which receives a mail, knows the token, and sends it to [notifications.delta.chat](http://notifications.delta.chat) could trigger a notification.

The tokens are stored via IMAP METADATA in this dictproxy: [server/chatmaild/src/chatmaild/metadata.py at main · chatmail/server · GitHub](https://github.com/chatmail/server/blob/main/chatmaild/src/chatmaild/metadata.py)  
which is run by a systemd service which is deployed here: [server/cmdeploy/src/cmdeploy/\_\_init\_\_.py at main · chatmail/server · GitHub](https://github.com/chatmail/server/blob/main/cmdeploy/src/cmdeploy/ __init__.py#L105)
