31 ;; MH-E is an Emacs interface to the MH mail system.
33 ;; MH-E is supported by GNU Emacs 21 and 22, as well as XEmacs 21
34 ;; (except for versions 21.5.9-21.5.16). It is compatible with MH
35 ;; versions 6.8.4 and higher, all versions of nmh, and GNU mailutils
38 ;; MH (Message Handler) is a powerful mail reader. See
39 ;; http://rand-mh.sourceforge.net/.
41 ;; N.B. MH must have been compiled with the MHE compiler flag or several
42 ;; features necessary for MH-E will be missing from MH commands, specifically
43 ;; the -build switch to repl and forw.
46 ;; M-x mh-rmail to read mail. Type C-h m there for a list of commands.
47 ;; C-u M-x mh-rmail to visit any folder.
48 ;; M-x mh-smail to send mail. From within the mail reader, "s" works, too.
50 ;; Your .emacs might benefit from these bindings:
51 ;; (global-set-key "\C-cr" 'mh-rmail)
52 ;; (global-set-key "\C-xm" 'mh-smail)
53 ;; (global-set-key "\C-x4m" 'mh-smail-other-window)
55 ;; If Emacs can't find mh-rmail or mh-smail, add the following to ~/.emacs:
56 ;; (require 'mh-autoloads)
58 ;; If you want to customize MH-E before explicitly loading it, add this:
59 ;; (require 'mh-cus-load)
62 ;; mh-e-users@lists.sourceforge.net
63 ;; mh-e-announce@lists.sourceforge.net
64 ;; mh-e-devel@lists.sourceforge.net
66 ;; Subscribe by sending a "subscribe" message to
67 ;; <list>-request@lists.sourceforge.net, or by using the web interface at
68 ;; https://sourceforge.net/mail/?group_id=13357
71 ;; https://sourceforge.net/tracker/?group_id=13357&atid=113357
72 ;; Include the output of M-x mh-version in the bug report unless
73 ;; you're 110% sure we won't ask for it.
