Chapter Introduction (Preface)

[next] [table of contents] [index]

The MH Message Handling System is a set of electronic mail programs in the public domain. If your computer runs UNIX, it can probably run MH. MH is free, powerful, flexible -- and the basics are easy to learn. This book starts with an introduction to electronic mail; if you've never used email, that's a good place to start. If you'll be using MIME multimedia email, read the introductory MIME chapter. Next is an overview and tour of MH 6.8.3. You can start sending and reading mail with MH right away, by following the examples and step by step instructions in the tour. In just a few pages, you'll have the flavor of the system and a hint of the advanced features. After the tour, a series of chapters give detailed information about using and customizing MH.

This book also covers three popular interfaces, or front ends, to MH. There's a step-by-step tour for each interface that will have you sending and reading mail within a few pages.

xmh is a way to use MH from the X Window System Version 11 Release 6. (xmh under X11 Release 3 is fairly different, but you shouldn't have much trouble using it with the instructions for Release 6. For a user, xmh with Release 4 and 5 is almost the same as the Release 6 version.) xmh runs MH commands with an X interface using windows, buttons, and a mouse.
mh-e is an interface to MH that runs from the GNU Emacs editor. It gives a windowing interface to MH from almost any terminal. mh-e commands are generally short and powerful. If you already use GNU Emacs, mh-e lets you integrate the flexible MH mail system into your Emacs environment.
exmh is a new and popular MH interface written with Tcl/Tk. Like xmh, exmh works under the X Window System. But exmh has many more features -- including support for sending and receiving MIME multimedia messages.

Other chapters build on these tours to show you more features and help you customize the programs if you want to. One Chapter explains how to program with MH -- to get the most out of it, you should have done some computer programming. There are useful programming examples sprinkled through the book. A Section explains the programs in this book's online archive file. But even if you've never programmed, you should be able to get most of these programs running with just a little help from a friend.
