The IP address?  It stays the same, regardless of the spoofed reply address.

Subject: [IMail Forum] WAY OT--Tracking Sobig


| Hi all,
|
| Those who don't want to waste their time on non-Imail issues please move
| on now...
|
| I have a connectivity customer who has an GroupWise mail server behind a
| Symantec Gateway.  Sobig isn't getting through to his mail server.
| However, the quantity is such that the Symantec Gateway is so overworked
| that his legit mail is suffering a massive slow-down.  He has observed
| that Sobig spoofs the sending address.  I observed the same when we got
| a message to an alias saying that the alias address had sent Sobig.
| He's wondering if there is a way to track it back and notify the owner
| of the infected machine and thereby hopefully reduce the volume they are
| receiving.
|
| I've asked him to send me the headers from a quarantined message so I
| can investigate.  His first attempt to do so was unopenable to me.  I'm
| awaiting his next attempt.
|
| Has anyone had experience or any suggestions for tracking Sobig?  I
| haven't seen any samples of Sobig.F.  YEAH for Imail rules!  Maybe not
| perfect but helpful, anyway...
|
| Thanks,
| Katie
