Microsoft: How can we help you?

How can we help you? A friend of mine called this morning to say that, despite the spamassassin I had installed, he had received almost 2000 spam messages and whether I could help. Not certain how one could receive suddenly so much spam I was somewhat bewildered and took an eager look. The spam turned out to be legitimate system messages of servers stating that the user-id was wrong, did not accept mail from unknown sources etc.
