So, I've been considering moving those checks to filter_end and having it generate tags that indicate the message should be treated as spam instead of being rejected.

What works fine for me is to do this checks just before calling SpamAssassin and add the result as headers to the mail that SpamAssassin checks.

This way I can have SpamAssassin rules scoring for things that looks like dynamic or dul hostnames. So a dynamic looking host name in itself won't stop a mail from beeing received, but it will increase the likelyhood of the mail beeing rejected.

(This kind of thing is why I patched mimedefang.pl so I can add my own headers to SpamAssassins input.)


I've just created a SpamAssassin Plugin that does it in SA directly. I'm still testing it. I'll put the code up for review soon.
