MH & nmh: Email for Users & Programmers

More Information About MH

Amazingly, not a lot has been written about MH. This book is the first work of this depth that I know of. Here are some ways to find out more about MH.

Documents Distributed with MH

The MH distribution has a directory called papers with tutorials, detailed descriptions of applications, and related programs. MH also comes with an Administrator's Guide, a good place to learn about installing MH and to discover some of its inner workings.

The MH Source Code

MH is written in the C programming language. One way to find out what it does is in classic UNIX hackers' style: read the code. Most of the code is clean and modular.

World Wide Web Pages

Here are some World Wide Web pages for the software.

Usenet Newsgroup

If you read the Usenet "netnews," the newsgroup is a good place to read about MH -- and post questions, if you have them. One place to read and post, as of mid-2003, was Google Groups at

Mailing Lists

The old mh-users and mh-workers mailing lists have been disabled. Articles from these mailing lists have been archived at SourceForge.

The mailing list is used by anyone interested in any aspect of the rand-mh project at SourceForge, which includes this book. This list also receives bug reports, feature requests, bugs, and check-in messages.

Here are two of the mailing lists about nmh:
