Help creating a mailing list

[barrett at crabcake.cs.jhu.edu]

	I plan to maintain a electronic mailing list, and I want it to work
in the following way:

	1)	People send mail to the list on my machine.  Suppose everyone
		sends to "foo-list at machine.name".

	2)	Each letter is held on machine.name, in some spool directory,
		until 3:00 am.

	3)	All letters in the spool directory are sent out at 3:00 am,
		to everyone on the mailing list.

	I can do this easily using a mail alias that pipes each mail message
to a unique file in the spool directory, and then have cron send everything
in the directory at 3am.  HOWEVER, all the Return-Path: and From: fields
will be wrong.  They'll all be "root", and I want them to be the fields
from the original senders.

	What's an elegant way to do this?  I really don't want to write my
own programs for extracting and using the sender's name, etc. etc.  We're
running ULTRIX 2.0 and sendmail on a VAX 8530.

	My main goal for doing this spooling is that I don't want to bog
down the machine with sending mail during the day.  There are about 50
people on the mailing list.  Maybe there's a better method entirely for
doing what I want...?

	Thanks very much!  Please reply by E-MAIL ONLY to any of
the addresses below.
