please help with mail routing

[Tony A. Facca]

Hello,

Q.  Can anyone help me setup a distribution list using Mail??

I am trying to setup a local "info-iris" for the people using Iris's here at
NASA LeRC.  What I have in mind is this:  users mail information, querries, 
etc, to a local machine which will serve as the distribution point.  From this
machine (which I happen to be root on), I want to be able to maintain a list
of all the user's who will receive the mail.  I then want the mailer to be 
able to forward this mail to each person on the distribution list.

Now, in the /usr/lib/Mail.rc file I can setup the list of aliases for the 
distribution list, and if I send mail to this alias it get distributed 
correctly.  The problem I can't understand is, how do I make the mailer
realize the INCOMING mail for this alias should also be distribute??  What
happens now is the mail get bounced back with an "user unknown" message. I can
alias the incoming message is /usr/lib/aliases to some userid (mine?) but then
I would have to join a user which seems pointless.  I don't know if there is a
way to use my userid as a forwarding mechanism for only a specific alias, and
not forward all the other mail I get.  

What do I need to do??  Please use file names and be explicit -- I have been
sifting through mail man pages for a couple days now.   I believe it must be 
some combination of /usr/lib/Mail.rc, /usr/lib/aliases and something else.  

Any suggestion would be appreciated.
