Documentation:
*Alternate spool files.

You can use the `mh-inc-spool-list' variable to direct MH-E to
retrieve mail from arbitrary spool files other than your system
mailbox, file it in folders other than your "+inbox", and assign
key bindings to incorporate this mail.

Suppose you are subscribed to the "mh-e-devel" mailing list and
you use "procmail" to filter this mail into "~/mail/mh-e" with
the following recipe in ".procmailrc":

MAILDIR=$HOME/mail
:0:
* ^From mh-e-devel-admin@stop.mail-abuse.org
mh-e

In order to incorporate "~/mail/mh-e" into "+mh-e" with an
"I m" (mh-inc-spool-mh-e) command, customize this option, and click
on the "INS" button. Enter a "Spool File" of "~/mail/mh-e", a
"Folder" of "mh-e", and a "Key Binding" of "m".

You can use "xbuffy" to automate the incorporation of this mail
using the Emacs 22 command "emacsclient" as follows:

box ~/mail/mh-e
title mh-e
origMode
polltime 10
headertime 0
command emacsclient --eval '(mh-inc-spool-mh-e)'

In XEmacs, the command "gnuclient" is used in a similar
fashion.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 7.3 of the MH-E package that is part of Emacs 22.1.
