pop3 email header classifier?

[Robin Becker]

Hi, I'm getting vast numbers of fake upgrade emails containing some kind
of virus. My rather old client can be made to reject these based on some
patterns in the subject line. They're nearly all based on the word
'New', 'Latest', 'Microsoft', 'Patch', 'Pack', ... etc etc.

Is there a python tool that can be made to delete these from my POP3
mail box rather than let my client reject? Quite a few seem to have
semi-valid return addresses so I get postmaster rejects from
xxx at microsoft.com etc.

I know about spam-bayes etc, but these things are over 120k each and it
seems pretty pointless to download them (as well as taking about an
hour).
