I'm running 7.0+ for about 2 months now on my private domain (ldap with a single-user, relay host configuration, fetchmail) using the docker-compose override feature. There was no migration needed for any of the in-container configuration files if I recall correctly.
There are some docker-configuration changes that might be relevant to you:
If you want to compare changes yourself: https://github.com/tomav/docker-mailserver/compare/v6.2.0...v7.0.0
(If you feel less adventurous, you can try to rebuild the 6.2.0 version to replace the /etc/supervisor/conf.d/saslauth.conf with your patched version and use docker-compose override too, but I assume you already do that.)
Hi @reneploetz,
would you be open to open a pr to update the mailserver container in this repo to the latest version (incl. your suggested changes)?
@reneploetz Thanks for the insights. I like a good adventure, but yeah, for now I did manually patch the saslauth.conf.
I'm propably going to update and test my homelab setup and see if anything comes up. Going to reply as soon as I have something running and ran some tests.
I wanted to ask if anybody attempted to upgrade the mailserver to 7.0 and if there are any known issues.
Reason for that is that there are a few changes made (e.g. a user-script.sh) which can be configured to change (e.g. sed) the generated config.
This is an issue, if you use a single domain authenthication setup, since saslauthd_rimap (part of mailserver) is configured with "-r" by default, which means the username will either be passed trough, if it contains an @ (eg. user@example.com) or appended with the hosts own domain (eg user => user@mail01.example.com). This will lead to the Samba4/LDAP auth to fail for smtp (submission to be precise), since the server expects "user" as the username, not user@mail01.example.com. See this issue. Works fine for imap though, since only postfix adds the domain before attempting to auth against imap.
Also today I discovered the saslauthd is logging quiet a lot, including the users password. I do not like that.
I hardly think the maintainers of the mailserver will backport anything to the 6.2.0 release, so...
