Adding allow_all_users to my userdb static args gets rid of the previous
error message, but now the logs contain this message:

Apr 10 11:48:28 mail deliver(user at domain.com): setgid(999) failed: Operation
not permitted
Apr 10 11:48:28 mail postfix/pipe[17576]: 95FC916872D: to=<user at domain.com>,
relay=dovecot, delay=0.31, delays=0.26/0.02/0/0.02, dsn=2.0.0, status=sent
(delivered via dovecot service)

999 is the gid of my vmail user.

I couldn't find a core dump file in the base_dir (/var/run/dovecot). Is
there a way to force a core dump?
