exmh uses several entries from your
MH profile (usually named
including several entries that are only for exmh.
- Header-Suppress: and Header-Display:
You control what header fields are displayed in a message with a
combination of the Header-Suppress: and Header-Display: profile
Hidden fields are just scrolled off the top of the message display
Each profile entry is a list of regular
expression patterns that are matched against the
Case is not significant in the patterns.
exmh takes three steps to decide whether or not to
show a header field.
Note that a pattern in Header-Display:
has priority over a pattern in Header-Suppress:.
The default values for these profile entries are:
By default, show all header fields.
If a field is in the Header-Suppress list, don't show it.
If a field is in the Header-Display list, show it.
Header-Display: subject to from date cc
If you are a mail junky, you may want to use Header-Suppress to
explicitly suppress the boring header fields you already
New, interesting fields inserted by random mailers will be
displayed for you to check out.
In contrast, the default for Header-Suppress hides
everything; you explicitly choose fields you want to
see by setting Header-Display.
So, the effect of the default rules is to show five fields:
Subject:, To:, From:, Date:, and cc:.
The Folder-Order: entry tells exmh how to order your
folder labels in the folder display area.
Each item in the order can be either:
All folder names that match the same pattern are sorted alphabetically.
Longer pattern matches have priority over shorter patterns.
the name of a folder, or
a glob pattern to match on the folder names.
The glob patterns use the syntax of Tcl's string match function.
It's similar to the string matching used in many shells:
* matches a sequence of any characters.
? matches any character.
The default Folder-Order: puts your inbox first:
Folder-Order: inbox *
My Folder-Order looks like:
Folder-Order: personal exmh mxedit * mail* sun m3 mach background
Folder-Order: also tells exmh the order in which to visit
folders that have unread mail.
When you use Next at the end of a folder, exmh
automatically changes to the next folder in
Folder-Order: that has unseen messages, if any.
When no more folders have unseen mail, you're changed
to the first folder in your Folder-Order: -- unless you disable
this by turning off the Cycle back to first preference setting
under the Scan Listing section.
The Folder-Unseen: entry lets you tell exmh the
names of folders to search for unseen messages.
Its value is a set of "glob" patterns that are matched against folder
Note that glob has filename smarts, so you'll have to take into
account subfolders in your glob patterns.
Key Parts of the UNIX Filesystem
explains how MH stores folders and subfolders
in the UNIX filesystem.)
Use inbox* to match all folders whose names begin
with inbox, but not subfolders of inbox;
use inbox/* to match the first level of subfolders under inbox;
use inbox/*/* to match the second level; and so on.
The Folder-Ignore: entry is a set of patterns for
folder names you want to ignore.
The default pattern is .*, which causes exmh to ignore all
directories whose names begin with a dot (.).
Your glob patterns for Folder-Ignore: must take subfolders
into account -- in the same way as Folder-Unseen:.
The Draft-Folder: entry is the name of a folder for messages
If you don't have a Draft-Folder: entry,
exmh asks if it may create one.
The Section Draft Folder
has more information.
The ExmhShowProc: entry lets you define a program that
pre-filters a message before displaying it.
If ExmhShowProc: is defined, exmh runs that program
with the current message as the standard input; exmh displays
the program's standard output.
Note that the Header-Suppress: and Header-Display:
mechanisms are used even if you have a special showproc.
The Scan-Proc: entry can be used to define an alternative
(For more information, see
the Section MH Format Strings.)
If you change the scan format, be sure that the message number
is first on each scan line and that there is at least one
space after the message number.
exmh depends on this.
The MailDrop: entry is required if you don't have your system
mailbox in the "standard" location, which is typically
If you don't define MailDrop: correctly then Inc won't do
anything because it won't find your new messages in the
The Path: entry is used to find your mail folders.
exmh aborts if this entry is missing; it presumes
that you haven't set up MH properly.
The Section Changing MH Directory Name
has more information.
