Hi all!

I recently upgraded the postfix package and made quite a few adjustments (e.g. using tmpfiles.d instead of a 1000 line POSIX shell script, splitting shared libraries and applying mild hardening on the postfix.service). As for many setups postfix is probably rather mission-critical it would be excellent to get some signoffs on it.

Specifically it would be good to test setups in which postfix is not handling virtual mailbox setups, but is using unix user setups (due to the changes introduced to the service file).

Best, David
