hm, already @ unlimited,

If you start Dovecot via "service", it probably overrides the ulimit in some script. Make sure you see:
cat /proc/pidof dovecot/limits|grep core
Max core file size unlimited unlimited bytes
Easiest probably just to start dovecot with:
ulimit -c unlimited dovecot
in master.conf ... service imap { protocol = imap executable = gdbhelper /usr/local/libexec/dovecot/imap ...
Well, with gdbhelper you won't ever get a core. I can't actually even remember how gdbhelper is supposed to work. Just don't use it.

This is no longer necessary at all with Linux.
