I have a literary account of my struggle with base64 spam at:
http://unrepentant.blogspot.com/
It prompted this comment:
You might want to look at moving away from Procmail recipes and SpamAssassin
to a pure Bayesian filter [PG's Plan For Spam]. Base64 encoding becomes a
spam-indicator if you get Base64 spam and no legitimate email Base64
encoded.
If you want a working version (with Bayesian noise reduction!) check out
DSpam.
(Full disclosure: I did a degree dissertation and project on Bayesian
filtering for spam killing).
