I use several procmail rules to filter out domains (microsoft.com,
msdn.com, etc.) in From: and From, To: (e.g. microsoft.com) and certain
words in the subject (e.g. Microsoft). Since the virus depends on
looking like an authentic message, it can't do too much randomisation of
the domains and subject lines. Of course the filtering is not perfect,
but it still reduces the number of virus messages hitting the inbox.

Someone pointed out yesterday that Swen has the header "SUBJECT: " in all
upper-case, as opposed to the usual mixed-case "Subject: ".  I looked at
all the ones I've received, and sure enough, they're all upper-case.  
That might be another telltale you can use if you're taking the procmail
approach.
