Anti-spam methods

Anti-spam software is mostly off-topic for Dovecot, since it is usually done on MTA side. Dovecot does have an way to allow users to train antispam filter by moving mails to spam/ham mailbox, but that's all. Still, this question gets asked once in a while, so here's a page where you're free to give your own opinion about different methods and software. The opinions expressed in this page are not the official opinions of Dovecot authors.
