systemd don’t need pid files, and the executable must be started without forking.
Can you show us the content fo the system dovecot.service file. As long as it contains this line, it should be fine:
Type=simple ExecStart=/usr/sbin/dovecot -F
Just before I saw your mail, I found now a solution.
The original dovecot.service has this:
[Service] Type=notify ExecStart=/usr/sbin/dovecot -F
which according to systemd.service man page needs a sd_notify() call from the running process. So somehow this is broken now?
I changed it to the following and now it works:
[Service] Type=forking ExecStart=/usr/sbin/dovecot
I don't know that much about systemd what of forking/exec/simple would be the best one.
The forking type exists mainly for compatibility with executables that are not able to start without forking.
When an executable as a « foreground » mode, it is usually recommended to use it instead.
The snippet I posted come from the official dovecot ubuntu distribution (from https://repo.dovecot.org https://repo.dovecot.org/) (that’s the one I’m using).
