Hi Johanners Berg,
I put the antispam plugin to work (some days ago) and now my imap daemon dies with segfault. I don't have nothing (wrong) in logs, just a lot of segfaults...

When I disable the antispam plugin, everithing works as normal...

I can't increase these number! I already alter the limits.conf, the ulimit.. and nothing seens to work... Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 1456). Either grow the limit or change login_max_processes_count and max_mail_processes settings
