You should be able to adjust the rules for NST and Spamassissin to filter most of them out.

Did you you update to the last version ? ( 2.3.5.3 )
There where some Sare-Rules added, which are sorting out those "embeded picture mails" ?

Then you should maintain your bayes database. ( If you use it, if not you should )
Are you learning HAM and SPAM, without any error messages ?
Can you run expire.bat ?
Sometimes the bayes database is corrupt or poisened. So, bayes is returning bad values.
You can delete the database and build up a new one.
If you delete it,
it takes some X00 Mails then bayes scoring will run again.
( First it has to sample X00 Mails, then scoring starts )
While learning SPAM you can watch the bayes Score going up for particular unwanted mails.
