Curiosity about this .pif spam/virus - nearly offtopic

Hi, One thing I noticed about this wave of spam with .pif attachments. They are destined for my address above (only used for SuSE lists) - so I know it is not a compromised PC of one of my friends, they don't know this address. Spamassassin flags them all as spam; and they come from bussineess addressess, with whom I never had bussinesses, like microsoft.com, and many others. I'm wondering if they are people on the adress book of my usual bunch of spammers! Ie, the people hiring the spammers. Serves them well, then. X-) On the other hand, it could be people reading this list with outlook, that got infected. Pity... they should have used linux. -- Cheers, Carlos Robinson
