http://dovecot.org/bugreport.html explains all of the things you need to
get core dumps. Although some of those settings are v1.x specific, so I
should look into updating the page..
Anyway, you can also test that you really get core dumps by manually
sending a SEGV signal to one test imap process.

The gdb backtrace will be enough.
