Hello list,

I have a postfix 2.11 with dovecot 2.2.5 instance. I have configured and installed anavisd-new to use Spamassassin. I want to train the filter. For that i choose dovecot's antispam plugin using mailtrain backend. I compiled and installed the latest version of the antispam plugin from http://hg.dovecot.org/dovecot-antispam-plugin/rev/5ebc6aae4d7c

The configuration is below.

Whenever I receive an email, the LMTP process segfaults. If I comment out the antispam plugin part in the config files, all works good. THis leads me to believe the issue is with antispam plugin, or its configuration.

Here is what i see in /var/log/mailllog
