Elfyn,
Let me be clear that I'm not accusing you (or Gareth or Chris F.) of
anything here. As others have pointed out, these worms are clever about
coming up with addresses both for the apparent "From:" address and the next
ply of intended victim recipients.
Here are the routing headers from the message _ostensibly_ from you:
Return-Path: <elfyn AT mail DOT utexas DOT edu>
Received: from mail18.svr.pol.co.uk (mail18.svr.pol.co.uk [195.92.67.23])

As you can see, although it claims (suggests? "From:" headers are
distinctly non-authoritative) you're at UT Austin, the message itself did
not originate or traverse any servers there. Nor does Hotmail appear in the
SMTP server-supplied forwarding header. (Concentric is my ISP.)
As I understand these worms, they use other user's address books (are they
called "Contact Lists" in Outlook and Outlook Express?) to come up with
both fraudulent "From:" addresses and recipients. Win32 DOT Bugbear AT mm uses
registry data to propagate, too.

Here's the full text of the message I receive (attachment graciously
elided--in fact, I delete them as soon as I confirm my hunch that they're
worms):
