Just checked on for the first time in 4 days or so, and I know it isn't me sending this one because i'm getitng auto-replies from folks who aren't even in my address book. For example, I got a bounce-back from support@jackpotauctions.com. I don't have them in my book, so there's no chance that a virus on my machine sent it to them. But there's another clue for anyone trying to figure out if you're the one sending it.

And yes, I update my Norton Virus signatures once a week.
