Actually, that's old school virus behavior.  A few years ago, they would 
look up the outbound relay from the mail client and use that to send their 
mail.  Recent ones have changed to sending direct.  My guess is malware 
authors found too many of the legit mail relays were running antivirus 
software hindering their efforts so they switched to sending direct.
