I'll take a guess. What can happen is Sobig sends a viral email as "user1", it bounces/is rejected and returns to "user1". However, the format of that bounce is the old-style Unix bounce: i.e. the original message is APPENDED to a bounce msg - not as an attachment - just banged onto the end of the file. Q-S won't spot the copy of SoBig as it's not an attachment any longer (and neither will Outlook BTW) - but some other AV systems do. Sounds likely? As I don't know of any MUA that'd even be able to see there was an attachment in that bounce, I don't really care that Q-S doesn't catch it. Not catching "corrupted" viruses doesn't seem much of a bug to me... -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
