+## Issues with Emacs 24 (unsupported since notmuch 0.31 (2020-09-05))
If notmuch-show-mode behaves badly for you in emacs 24.x try adding one of
application/pdf; /usr/bin/mupdf %s; test=test "$DISPLAY" != ""; description=Portable Document Format; nametemplate=%s.pdf
application/x-pdf; /usr/bin/mupdf %s; test=test "$DISPLAY" != ""; description=Portable Document Format; nametemplate=%s.pdf
+### Convert ".pdf" and ".docx" to text and pop to buffer
+
+Add the following (hacky but effective!) code to `.emacs.d/notmuch-config.el`;
+the overwritten `defcustom` will change action when pressing RET on top of an
+attachment; ".pdf" and ".docx" attachments are converted to text (using
+"pdf2text" and "docx2txt.pl" commands to do the conversion), saving to file
+(the default action of `notmuch-show-part-button-default-action`) is offered
+to attachments of other types.
+
+ (defun user/mm-pipe-- (handle cmd)
+ ;; conveniently, '-' '-' a args to pdftotext and docx2txt.pl work fine

## Overwriting the sender address
If you want to always use the same sender address, then the following
Messages can be signed using gpg by invoking
`M-x mml-secure-sign-pgpmime` (or `M-x mml-secure-encrypt-pgpmime`).
These functions are available via the standard `message-mode` keybindings
-`C-c C-m s p` and `C-c C-m c p`. To sign outgoing mail by default, use the
-`message-setup-hook` in your `.emacs` file:
+`C-c C-m s p` and `C-c C-m c p`.
+
+In Emacs 28 you will be asked whether to sign the message using the
+sender and are offered to remember your choice. In Emacs 27 you will
+get a slightly misleading error and have to manually add the following
+line to you init file. Older Emacsen just do this unconditionally.
+
+ (setq mml-secure-openpgp-sign-with-sender t)
+
+To sign outgoing mail by default, use the `message-setup-hook` in your
+init file:
;; Sign messages by default.
(add-hook 'message-setup-hook 'mml-secure-sign-pgpmime)
- (setq mml-secure-openpgp-sign-with-sender t)
This inserts the required `<#part sign=pgpmime>` into the beginning
of the mail text body and will be converted into a pgp signature
