My guess is: you call spamassassin also from .procmailrc (or something  
similar), and your $SALocalTestsOnly is set to the default (true), so  
you're not doing network tests. Certainly the first spam that you  
pointed to, has a lot of network tests.

Setting "$SALocalTestsOnly = 0;" in your filter will probably fix some  
of the spam that's coming through.

Also, be aware that setting up Bayesian filtering is not trivial. You  
can use a global bayesian database (and for starters, simply copy the  
one that's in your homedirectory), but you must remember to train that  
database, if you want bayesian filtering. I don't have the recipes  
handy for setting up Bayesian filtering via mimedefang, but either the  
manpage, the archives for this list, or the wiki should provide enough  
information to get it working.

Also, you'd better search for that spamassassin call in your local  
delivery agent (procmail?) and disable it (cause currently your mail  
server is pushing each message through spamassassin twice).
