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. -- Brent J.
