I see from:
 X-Mailer: Mutt 0.95.4i
that you're probably a Unix user (gratz); but Windows clients do things
like hide known extensions.  So foo.jpg.vbs would be shown as foo.jpg --
quite sick, yes.  When forced into using a Windows box, I change that
setting fast.

BTW -- there are security holes in _your_ email client.  You might wish
to upgrade.  ;^)
