openzfs-docs VS docker-mailserver

12 Feb 2024, https://www.phoronix.com/news/OpenZFS-Encrypt-Corrupt and https://github.com/openzfs/openzfs-docs/issues/494

> A new ticket has been opened for OpenZFS as well in proposing to add warnings against using ZFS native encryption and the send/receive support in production environments.

  "Among experienced zfs users and developers, it's conventional wisdom that zfs native encryption is not suitable for production usage, particularly when combined with snapshotting and zfs send/recv. There is a long standing data corruption issue with many firsthand user reports...Additionally, if you join #zfs or #zfsonlinux on freenode and mention that you're having an issue with zfs native encryption, you'll be met with advice from developers that zfs native encryption is simply not reliable."

I'm a little sad to see this. I've been using ZFS on my PCs for years with minimal issue and significant benefits. [1] I've even contributed [2]. And I remain a huge fan.

I don't believe that "everyone is just guessing". There are some pretty knowledgeable folk that work on this.

[1] I've triggered some corruption in snapshots on an encrypted pool. No permanent problems resulted and no data was lost.

[2] I provided a very minor documentation fix that was encouraged and promptly merged. https://github.com/openzfs/openzfs-docs/pull/472

- Don't give up to early and switch distro, if something does not work - try to do your research first and then stick to your choice

For everyone who's interested, I ended up using Artix Linux (Arch, no systemd) with encrypted ZFS on boot and KDE as desktop environment, and I'm pretty happy so far. Resources I recommend are:

Just bricked my trusty EliteBook 820 G3 while testing Secure Boot.

This is the closest I've found: https://github.com/openzfs/openzfs-docs/pull/21

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
