My wife's e-mail (Outlook Express on a Win-XP system) is receiving hundreds of "Mail Delivery Failure" messages every day for e-mail she never sent to names that are not in her address book and that she otherwise does not know.  There is nothing related to any of these returned e-mails in her 'Sent' folder.  Most of these e-mails appear to have a .dat file of a couple of hundred bytes or so attached.  Her e-mail address appears to have been spoofed into the 'Return-Path'.


Does this indicate a virus in her system somewhere receiving e-mail addresses from some bot somewhere, sending them from her computer, and somehow avoiding copies to the 'Sent' folder?  Aside from manually deleting the returned e-mails, is there anything that can be done to keep them cleaned out automatically (a filter of some sort?) and to fix whatever is causing this to happen?

I'm moving this topic to the Am I Infected forum.  It sounds as though her e-mail address has been compromised and something is sending out spam in her name.  I'd immediately go to a known clean computer and first change any passwords associated with the e-mail accounts.  Second, I'd see if I could get the user name changed.  It's possible that her e-mail address was compromised on the internet itself.  That happened to me when I didn't even HAVE a computer.  Since then, I've learned not to post my e-mail address on the internet anywhere.


Another possibility is that the e-mail address was compromised on someone else's computer.  In other words, someone she communicates with and has her e-mail address saved in their computer has an infection on that computer.


We do need to determine, however, that her computer is infection free.
