I have a webmail application that can be made to delete messages based on
regular expressions, at http://entrian.com/cgi-bin/pop3.py

I wrote it in response to a similar problem, whereby a spammer used my
address as his From address, and I received a couple of thousand bounce
messages a day.

You can set up regular expression filters on To, From and Subject, and set
it to either mark messages for deletion (so you get to review them before
deleting them) or delete them straight away (via the "I'm either brave or
stupid" checkbox, TM 8-)  You can save your filters for later use.

Take EXTREME CARE with this, particularly if you check the "I'm either
brave or stupid" box.  8-)  There is no way to recover a deleted message.
Don't sue me if it eats your hamster's emails.

You probably need something like (untested):

From: microsoft|ms\b
Subject: patch|latest|microsoft|update|upgrade|pack

There's no SSL version of this, so your POP3 account details will pass in
plain text over the internet (in theory my provider has a scheme whereby
you can access the site over SSL using their certificate, but it doesn't
work for some reason - if there's any interest I'll see whether I can make
it work).

(And no, I'm not going to harvest your POP3 account details.  They never
even hit the hard drive.)
