Of course, this sort
of spoof will only work on mailers such as mutt where you cannot
clearly tell PGP output from message content (and you have to pay attention
to other cues, such as the "s" flag shown in the mail folder listing).

Also, in mutt, pgp signatures are displayed as attachments (or in my
config they are).  Your "spoof" was displayed as plain text and not
highlighted as an attachment.
