Hi Roberto,
thanks for the careful testing.
I found a solution for the problem and I think it is a problem in the package (likely not introduced by your patch though). I think your testing went well, because you did not upgrade while dovecot was under heavy load, but in your test installation dovecot was probably idle.
I noticed that Dovecot started always immediately after stopping it again:
Aug 31 19:24:22 netcup systemd[1]: Activated swap /dev/vda1. root@netcup:~# invoke-rc.d dovecot stop Warning: Stopping dovecot.service, but it can still be activated by: dovecot.socket root@netcup:~#
it says dovecot can be activated again by dovecot.socket, when stopping dovecot the way the pre-rm script does it.
I then stopped dovecot.socket first and dovecot.service second:
root@netcup:~# systemctl stop dovecot.socket root@netcup:~# systemctl stop dovecot.service
This really stops dovecot

Many thanks again Roberto and Mike for looking into that and helping to get the issue resolved.
