What attachment?

I'm seeing this:

<snip headers>
X-Mailer: Sylpheed version 0.7.6 (GTK+ 1.2.10; )
Mime-Version: 1.0
Content-Type: multipart/signed; protocol="application/pgp-signature";
<snip headers>

and this:

I  1 <no description>              [text/plain, 7bit, US-ASCII, 1.7K]
I  2 <no description>                [applica/pgp-signat, 7bit, 0.2K]

So we've got text, and a PGP signature. Not any attachment, in the
sense that Johannes means, and most people thing "email attachment" to

It may have something more to do with your MUA:

<snip other headers>
X-MSMail-Priority: Normal
X-Mailer: Microsoft Outlook Express 5.50.4807.1700
X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4807.1700
<snip other headers>

...and PGP.

Now, Mutt invokes PGP automatically, so I don't have to *do* anything
when I merely read a PGP-signed email...
