Posted to comp.mail.sendmail.

Hello there, first off let me say I don't know anything about sendmail.

However, I have a NeXT (sendmail 565c) connected to the internet thru my host
gate.demon.co.uk

Currently, all mail just gets forwarded directly to my host and then
my host takes care of it from there on.

This is what this sendmail file is doing I believe.

Anyway, I am now supporting a mailing list and would like to set
things up so that I have JUST 1 transaction for all recipients on
that list for any message on the list.  Currently, I have n
transactions where n is the number of users on the list.  This is very
costly and inefficient. (to say the least)

Just by browsing this are you able to come up with anything that
allows me to work this way?
