### 1.2 Non-MIME

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))

`postscript`
  PostScript file.
`uu`
  Uuencoded file.
`binhex`
  Binhex encoded file.
`yenc`
  Yenc encoded file.
`shar`
  Shar archive file.
`forward`
  Non-MIME forwarded message.
`gnatsweb`
  Gnatsweb attachment.
`pgp-signed`
  PGP signed clear text.
`pgp-encrypted`
  PGP encrypted clear text.
`pgp-key`
  PGP public keys.
`emacs-sources`
  Emacs source code. This item works only in the groups matching `mm-uu-emacs-sources-regexp`.
`diff`
  Patches. This is intended for groups where diffs of committed files are automatically sent to. It only works in groups matching `mm-uu-diff-groups-regexp`.
`verbatim-marks`
  Slrn-style verbatim marks.
`LaTeX`
  LaTeX documents. It only works in groups matching `mm-uu-tex-groups-regexp`.

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.
