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.)
