nmh (new message handler), is a powerful electronic mail handling system. Following the Unix Philosophy, nmh is made up by a collection of simple programs each of which has a single purpose. This architecture allows the user to intersperse nmh with other commands at the shell prompt and to write scripts tailored to their needs.

Optionally install a utility to handle IMAP or POP, for example, or AUR.

nmh is extensively configurable in a variety of ways. The primary of these is the
The syntax for
~/.mh_profile is unusual. For example, nmh will refuse to run if there are blank lines in the file. Read the page for more.
By default, nmh uses
- Path can be either full (if prefixed with
/) or relative to $HOME.
- Nmh uses the mh mail format, which is different from the maildir and mbox. Setting your Path to a preexisting maildir folder, for example, will not work.
Set inbox (relative to Path):
Also by default, nmh populates the mail folder with the
inc command, which incorporates mail from the user's mail drop (
If you have a non-standard mail drop path, you can set an environment variable
$MAILDROP, or set MailDrop in
or set inc:
inc: -file /path/to/mail-drop
command: -flagformat in mh_profile. These work much like bash aliases.
Nmh is also capable of retrieving mail via POP. A basic POP setup (seefor more):
inc: -host example.com -user username -sasl
To become familiar with basic nmh usage, learn and practice the following commands:
|inc||Incorporate new mail.|
|scan||Scan the contents of the current folder.|
|folder/folders||Change the current folder or list folders and their contents.|
|comp||Compose a new message.|
|repl||Reply to a message.|
|refile||Move a message to another folder.|
While nmh is fully usable from the command-line, several console-based and graphical user interfaces exist. Also, some common mail tools interact smoothly with the mh format.
- MH-V, a console interface to mh/nmh with vi- keybindings.
- MH-E, a console interface to mh/nmh with Emacs keybindings.
- exmh, a TK-based mh GUI.
- Popular MUA mutt understands mh format. (Use
set mbox_type = mhin your muttrc.)
- Full-text mail indexer and search utility mairix can read and write in mh format. (Use
