Welcome to the home of nmh, on savannah.nongnu.org.
The latest stable release of nmh is nmh 1.6. You can download it from savannah.
We are pleased to announce the start of the release cycle for nmh 1.7 on August 2th, 2017. The latest release candidate for nmh 1.7 is nmh 1.7-RC3. You can download it from savannah.
Nmh 1.7 contains a large number of bug fixes and new features. The release notes (see the NEWS file in the distribution) has a complete list of new features, but here are some highlights:
- Complete unification of network security support. All network protocols (currently, POP and SMTP) have been refactored to use a common set of security routines. This means all protocols support all SASL mechanisms (via the Cyrus-SASL library) and TLS. TLS support has been strengthened to perform certificate name validation and to require TLS 1.1 as a minimum protocol. Also, all protocols can make use of the OAuth2/XOAUTH SASL mechanism, which is supported by gmail.
- send now supports adding switches to post based on the address or domain of the email address in the From: header; this more easily allows users to support multiple identities.
- A generic facility for passing arguments to filter programs in repl by the use of the -convertargs option.
- Native support for the manipulation of iCalendar requests; see mhical(1) for more details.
Please report problems in the bug tracker on savannah, or on the nmh-workers mailing list. Thanks!

nmh (new MH) is a powerful electronic mail handling system. It was originally based on version 6.8.3 of the MH message system developed by the RAND Corporation and the University of California. It is intended to be a (mostly) compatible drop-in replacement for MH.
nmh consists of a collection of fairly simple single-purpose programs to send, receive, save, retrieve, and manipulate e-mail messages. Since nmh is a suite rather than a single monolithic program, you may freely intersperse nmh commands with other commands at your shell prompt, or write custom scripts which use these commands in flexible ways.
NOTE: All versions of nmh prior to 1.0.3 (as well as MH) contained a vulnerability where incoming mail messages with carefully designed MIME headers could cause the mhshow command to execute arbitrary shell code. Though the authors of nmh are not aware of any exploits of this hole, MH users and users of older versions of nmh are strongly encouraged to upgrade to the current version.
- The git repository is available for anonymous checkout using the following command:git clone git://git.savannah.nongnu.org/nmh.git
- You can also browse the source code with a web browser.
There are three mailing lists for NMH, hosted by Savannah.
- nmh-announce is a low-volume list for announcements about nmh.
- nmh-workers is the main list for users and developers of nmh.
- nmh-commits is a list which will receive notifications of changes to the nmh source code tree.
- The mutt email client does a good job with MH folders.
- UW IMAPd has basic support for reading MH folders.
- mairix is a full-text mail indexer that understand MH folders.
- A lot of other compatible tools are listed in section 01.05 ("other MH software") of the MH FAQ
