I was getting about 50-80 of those a day myself for a while... I wrote
a perl script to parse a .spam file containing one regex per line.  If
any of the regexes in the .spam file match the author or subject in
the mail on the server, it's deleted on the server.  I mainly just
focused on the service packs as they took so long to download.  I'm a
perl novice, so I'm sure this code could be reduced to about 10 lines
by someone that knows the language better.

Here's a snippet from my .spam:

critical.*update
critical.*upgrade
customer.*bulletin
public.*assistanc
internet.*system
security.*pack
security.*update
security.*patch
delivery.*system
microsoft

And the script (I called pop-spam.pl) I just call with no arg for
preview: 'perl pop-spam.pl', and 'perl pop-spam.pl delete' when I'm
certain of my regexes.
