Re: [vox] Spam question



I really think that it is probably the klez worm
One of the best antivirus sites is run by Trend.
www.antivirus.com

Link to the Klez virus
http://www.trendmicro.com/vinfo/virusencyclo/default5.asp?VName=WORM_KLEZ.H
Look in the Tech Details tab for details.

The problems with the Klez virus is that the original
sender is only located in the Evelope From field. 
There are a some email systems that will strip this
information (Exchange) and use the forged header info,
so that you will not see it.  The NDR will read the
forged name and bounce the email back to you.  I am
fortunate in that I block executable type attachments
and I have a front end system before it gets to my
Exchange server.

If the NDR has the original message then you can
compare it to the Tech Details description of posible
subj lines and see if it is Klez or one of it's
varients.

I get 10-20 bounces a day at work and my conterpart at
the bigger division gets LOTS more.

The header info of the NDR will only have the path from
the postmaster of the system sending you the notice.
