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.
So, if I would debug the antispam plugin, adding more log messages, finding the reason it doesn't work now, would my changes be included in the antispam distribution? Do you know any documentation about the Dovecot plugin API? I couldn't find any.
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.
Thanks for the hint. This looks interesing, but also quite complicated. I've read the two pages you specified. Is there any good documentation? I have Peer Heinlein's Dovecot book. But there isn't much in it about plugins.
