encrypted.asc is what Enigmail uses when sending using PGP/MIME. I think
it wraps up the message body in this file (armor encrypted) and marks it
with disposition inline. Enigmail also sends PGP/MIME version
identification information in another MIME part
(application/pgp-encrypted) - so you have two MIME parts per PGP/MIME
encrypted message.

You can view all headers in the test message if you're in notmuch-show by
using V. You'll see something like:

Content-Type: multipart/encrypted;
 protocol="application/pgp-encrypted";
 boundary="xxx"

This is an OpenPGP/MIME encrypted message (RFC 4880 and 3156)
--xxx
Content-Type: application/pgp-encrypted
Content-Description: PGP/MIME version identification

Version: 1

--xxx
Content-Type: application/octet-stream; name="encrypted.asc"
Content-Description: OpenPGP encrypted message
Content-Disposition: inline; filename="encrypted.asc"

-----BEGIN PGP MESSAGE-----
Version: GnuPG v2
...
-----END PGP MESSAGE-----

--xxx--
