App for email backup - imap

[hakamairi]

I'm looking for a way to backup my gmail and some custom imap servers to TrueNAS scale.

Found some topics on forums that recommended imapsync (https://github.com/imapsync/imapsync/) but this seems to sync data between two imap servers, not to mention that they were for TrueNAS Core.
In my mind that would do a DB like backup, full, incremental with option to restore.

Taking this into account I found
- https://github.com/joeyates/imap-backup
- https://github.com/GAM-team/got-your-back/wiki
They both seem maintained

Sadly I haven't found apps in official catalogue nor TrueCharts. I'm now to TrueNAS, but I know some docker.

Is there an app for that?
If no, how do I do that in TNS? Is there any guide or recommendation for creating new docker images? Or maybe there's another way to tackle this?

If I remember correctly, Paperless-ngx has the ability to archive emails from IMAP accounts, certainly as they come in. I think Nextcloud might be able to do it too, though you'd need to find the app through Nextcloud itself..

I am certainly into this also. I know of implementations with getmail() on Debian but not FreeBSD... but we shall dig for more and post it here...

You could run a dovecot docker image. Dovecot is the standard IMAP server for Unix systems. Then run that imapsync script on the TrueNAS SCALE host as a cron job. Some assembly required, batteries not included.

Keep the dovecot IMAP store an a mounted volume and snapshot that. Voila - backup of a remote IMAP account.

I would definitely go that route if I was set to that task. Although I would use a CORE jail instead of docker.
