Subject: Does Swen forge the sender? WARNING - LONG POST
In deference to the experts, Joe and Nick, rather than argue about what
Swen does, I'll just post some headers and ask for a *brief* explanation of
them.
1st header is a "bounce" to my work account. Unfortunately the bouncing
party didn't bother to include the original message headers, but it's
evident that they *thought* that I sent them the virus. Since the "From"
address was "Microsoft Security Support"
<dyfotwrltwosb_whweemsf@...letin.msn.com>, how does this get back to me
unless the "MAIL FROM" command was "pauls@...allas.edu"?

------------------ Virus Warning Message (on mail.cosmofilms.com)
Found virus WORM_SWEN.A in file Pack6579.exe
The uncleanable file is deleted.
---------------------------------------------------------
The second message is a "bounce" from Swen itself. Interesting that it has
an attachment which does not show up in Outllook Express because I force
plain text for all incoming messages. If I understand what you are saying
correctly the infected party should be "mdrake8@...lsouth.net", correct?
That *does* appear to be the case, since the mail originated at bellsouth.

The third message is an actual copy of Swen sent directly to my home
address. (I can't get any at work since we bounce them all.) Again this
appears to be from pratsc@...ra.es who's computer is infected.
