Actually, I am starting to get "rejected e-mail" which I supposedly sent (and from my attbi.com address which I have not used for months now) to people I don't even know and I don't have on my e-mail list. I simply delete these as they come (one of them had a .pif attachment, which of course I discarded, it is definitely associated with the sobig). I think my e-mail address was simply scooped out and set as an artificial sender in this virus attack.... Some of the "non deliverable" are to "wrong address", others are returned because the target IP identified a virus and would not forward. Frankly, a lot of wasted time on that thing.
