Gnus also
understands some non-MIME attachments, such as
postscript, uuencode, binhex, yenc, shar, forward, gnatsweb, pgp,
diff. Each of these features can be disabled by add an item into
mm-uu-configure-list. For example,
(require 'mm-uu)
(add-to-list 'mm-uu-configure-list '(pgp-signed . disabled))

Some inlined
non-MIME attachments are displayed using the
face mm-uu-extract. By default, no
MIME button for these parts is displayed. You
can force displaying a button using K b
(gnus-summary-display-buttonized) or add
text/x-verbatim to
gnus-buttonized-mime-types, See MIME Commands.
