sanoid VS docker-mailserver

I’m on the other end of the spectrum. I like knowing the flags and settings I use to create the pools.

For snapshots and replication take a look at sanoid (https://github.com/jimsalterjrs/sanoid).

I use a combo of PBS and ZFS with Sanoid. The ZFS snapshots are nice because you define it all in a config file with frequent, hourly, daily, weekly, monthly snaps retained however you want. Importantly I use that on the root pool as well as my data pools. With PBS I have a custom retention config and have it backing up VMs and LXCs every couple hours. The PBS dedupe functionality makes it possible to keep full backups going back ages with minimal storage consumption, just the changed blocks. PBS is running inside a VM yes, but it’s storage is on another pool.

No, it's written by the developer of Sanoid and Syncoid. The foremost open source ZFS snapshotting tool. He contributes on this sub all the time.

Hi there! Not so much to answer your questions, but are you aware of Sanoid and syncoid? It does backup and remote Sync in the most seamless way. Perhaps this would solve some of your concerns...

I can recommend Docker mailserver (it also works with Podman). It is already pretty lightweight but you can even make it lighter and it has an active community as well as regular updates.

https://github.com/docker-mailserver/docker-mailserver https://docker-mailserver.github.io/docker-mailserver/latest/ https://www.programonaut.com/how-to-host-a-mail-server-with-docker-for-free-step-by-step/

Use https://github.com/docker-mailserver/docker-mailserver or mailcow . They both provide reasonable default setup for spam detection and even UI for adjusting settings.

" this docker based mail server looks pretty legit https://github.com/docker-mailserver/docker-mailserver "

Check https://github.com/docker-mailserver/docker-mailserver It has almost everything in a single docker image. Email is not the easiest to implement with container(s), but that project has managed it.

I set up docker-mailserver[0] Monday in ~6 hours, most of which were me trying to be fancy using podman instead of docker and dealing with SELinux. But then again I did choose it over mail-in-a-box for just that level of customization. Obviously I can't tell how reliable it will be in the long run yet, but since it's using the classic Postfix/Dovecot stack I expect it'll be pretty stable
