Hi!
"Dovecot always logs a detailed error message if something goes wrong. If it doesn't, it's considered a bug and will be fixed." (http:// wiki2.dovecot.org/Logging)
Yes, that is indeed what Dovecot and Pigeonhole do. However, AntiSpam is not part of the normal Dovecot distribution, nor is it a plugin created by Dovecot developers. From what I know, Dovecot has mirrored/hosted the AntiSpam Mercurial repository in the past and contributed a few small fixes, but nothing more. Also, it doesn't look like it is actively maintained at the moment.
Pigeonhole Sieve recently gained support for the IMAPSieve extension (http://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/IMAPSieve). When combined with the exprograms plugin (http://wiki2.dovecot.org/Pigeonhole/Sieve/Plugins/Extprograms), you should be able achieve something quite similar using a Sieve script, although I have never tried that myself.

Stephan.
