Matt, I've been getting 2 or 3 a day... someone/thing is scooping addresses off the 'net and stuffing them in the 'reply to:' field of the emails. When you think about it, email is a prety unsecure medium. All ISP's should require secure login to send, as well as receive. I NEVER get spoofed like this on my attglobal account.
Anyway, thanks for the link to the sobig fix (that you posted in another of your posts). I DID confirm I don't have it. (I would flog myself for a week if I did. I know better)
