I've seen Sergio before, several years ago, in relation to my .Mac account.

Google for that phrase (sergio52 at mac.com) and look in the Apple Support
forums. I don't remember the answer -- it was at least two years ago, if not
longer -- but I know I found the explanation/answer either on Google or in
the Support Forums.

I was using Entourage, so it's not limited to a message only from Mail -- is
the account you're trying to use to send a .Mac account?
