This is the standard Emacs frontend to Rand Mail Handler, aka MH. MH is a mail user agent (MUA) for unix shell environment. Instead of being one monolithic program, all functionality is provided by a collection of small tools. Thus one uses one’s shell itself to drive it, and because of the way the messages are each in their own file, and folders are implemented as file-system directories, any general command can be used too in the most natural, UnixWay. The modern MH implementation is called “nmh”. It lives at Savannah, and has a homepage at http://www.nongnu.org/nmh.
Other, non-Emacs frontends to MH are the various shell commands (see the manpages for nmh(1) or mh-chart(1) for a list of the available commands), the basic X11 xmh(1x) and exmh, written in Tcl/Tk. Exmh homepage is at http://exmh.sourceforge.net/. Another Emacs interface called tmh was written by ThienThiNguyen, but since it hasn’t been updated since late 1994, it ought to be considered of historical interest only. It has been archived at the author’s webpage at http://www.gnuvola.org/software/tmh/.
We all know this is not the place to get into a MuaWar (though reasonable ComparisonOfMuas would be fine) but let’s face it, MH-E r0xx0rz and h@Rd! It also has been blessed by inclusion with both flavours of Emacsen, and thus is Good.
The MH-E homepage is on SourceForge, at http://mh-e.sourceforge.net. MH-E has it’s own InfoMode documentation which comes with Emacs. The most recent version is 8.0 which is now being kept in sync with the released version of the software. 
In many MH-E submodes `?’ (
‘mh-help’) provides a quick list of some the most common keybindings.
Then there is the book O’Reilly book by Jerry Peek entitled “MH & nmh: Email for Users & Programmers” which is freely available at http://rand-mh.sourceforge.net/book/ (massive props to Jerry). It used to have a chapter on MH-E, but the official documentation included with Emacs has supplanted it due to Bill Wohler’s hard work.
Several mailinglists exist on SourceForge, namely “mh-e-announce”, “mh-e-devel” and “mh-e-users”. All of these are bidirectionally gatewayed via the marvellous Gmane, which lives at http://www.gmane.org. Through this service one can access the lists not only with HTTP (SourceForge provides this too), but with NNTP. Fancy that! Contact the NNTP server news.gmane.org or see webpage http://dir.gmane.org/index.php?prefix=gmane.mail.mh-e for a directory of all related groups. The archives make a good read.
When configuring, it is often a GoodIdea to tweak the natural files of mh itself, the
.mh_profile for example. This is the general way to configure things, and all the changes will inherit to any frontends. If you shun such a blasphemous suggestion, remember that this is only a suggestion of an UnixZealot who wishes to a) also use mh via shell, and b) digs generality. So go ahead, just fiddle with the mh-* variables if you feel like it. Of course there are many options which make no sense to mh itself, and these frontend-specific things are to be set within the frontend itself. Like any large and decent EmacsLisp package, MH-E has it’s own group for the common user-friendly CustomizingAndSaving interface Customize to be accessed with the
If you’d like to configure MH-E to be your preferred mail-composing system, set the MailclientConfiguration variable
'mh-e-user-agent. If you’re using the GnuEmacs, you can also prefer MH-E for reading your mail, by setting
Some other folks around here are pretty fond of it as well! —JerameyCrawford
msmtp is useful when you have more than one mail addresses. It reads “From:” field and uses corresponding account. Should be built with GNU TLS support to be used with gmail (make WITH_GNUTLS=YES).
Assuming you have already installed nmh, fetchmail and msmtp.

mts.conf (mine is here: /usr/local/etc/nmh/mts.conf):

#!/bin/sh # can't just write "sendmail: /usr/local/bin/msmtp --read-envelope-from" in mts.conf # so it's a little workaround # makes msmtp to read "From:" field and to use corresponding account /usr/local/bin/msmtp --read-envelope-from $*

Also place “From: Your Name <firstname.lastname@example.org>” before “To:” in these files in ~/Mail: components, replcomps, forwcomps. After that you can send your mail using any of your accounts by editing “From:” field in your mail composing buffer.

ThawtePremiumServerCA.crt for gmail support in msmtp you can get here (I renamed ThawtePremiumServerCA_b64.txt) : https://www.verisign.com/support/thawte-roots.zip

For lazy guys here are three certificates, ~/.certs/gmail.pem:

Important! Do not forget to “$ c_rehash ~/.certs/”
MhBiff is apparently a mail-notification tool, with a Japanese webpage at http://www.yynet.tama.tokyo.jp/~yokota/mh-biff/ (editors note: anyone with a more fluent Japanese than my anime-japanese care to summarize the contents of that page onto MhBiff?). MhCrypt, Lisp:mh-crypt.el, is an utility to store the messages in an encrypted format. With a quick glance it seems this would break mh outside of MH-E.
For those who do not understand japanese well, there is another way to get mail notification: (display-time) function with some tweaks (useful in case of multiple mail folders)
;; Notification stuff: use display-time minor mode to notify about new mail ;; in mode-line, but omit time and load info. Print comma separated list ;; of folders with new mail in mode-line. (setq display-time-mail-function (lambda () (let ((input (shell-command-to-string "/usr/local/nmh/bin/flist -all")) (dirs nil) (start 0)) (while (string-match "^\\([a-z-+]*\\) *has [1-9].*$" input start) (push (match-string 1 input) dirs) (setq start (match-end 0))) (setq display-time-mail-string (mapconcat 'identity dirs ", "))))) (setq display-time-interval 10 display-time-format "" display-time-default-load-average nil display-time-mail-face 'custom-themed) (display-time)
