[mike at mrgfd.org.ua]

Hello! 

I have port-built dovecot-1.1.1 on freebsd 6.3 i386 box.

There is signal 11 on imap child occurs every time when i'm trying to send
email.
In fact, email is sending to MTA correctly, but when message moving to Sent
folder segmentation error appears.

I built dovecot and antispam plugin with -g3 -O0 -pipe

With GDB I recieve next:
