Base64 encoded spam

Currently, my usually double-hard spam filter is struggling with about 95% (up from < 0.01%) of the spam I receive. It appears that spammers have discovered that using Base64 encoded emails renders the current crop of spam filters (such as apple mail) useless. hopefully this gets fixed soon.

What about if you set up a message filter that checks for a base64 encoded email, since nobody is likely to send you emails like that often, unless they have attachments, but they are easy to differentiate since they will be multipart messages, one part of which will be text/plain or text/html.

After a bit of a muck around it seems that unfortunately mail.app's filter rules don't consider the fact that the users who look there might not be novices and allow technical rules. (Despite the fact that to find it you need to look in preferences → junk mail → advanced)

I wonder if it is possible to write an applescript rule or perhaps a mail plugin…
