For what it may be worth on this subject, I have recently been receiving notices of rejected IN-BOUND email TO me. The same kind of notices I receive when I SEND an email but type the address wrong. The failure notice states that the "sent email was infected with an incurable virus." And, of importance here, all have been from a cox.net address. In one case, I was able to recognize one of the senders as one of my cousins! I went the "old fashioned way" on that one and called her on the phone -- as I have no-charge long distance service.

Bottom line here is that I think that there is something wrong with cox.

Hope this helps,
Richard
