A novice question:

I have a little problem.  I run a moderated digest on a sun and the
address list is kept in one of my directories with 
  consdist: :include:~whenry/Mail/consdist 
in  /etc/aliases

when I send out a mailing, I tack on headers such as
  To: consdist
  Reply-To:whenry@lindy.stanford.edu
  etc.
and send it with /usr/lib/sendmail -t

Everything would be fine except that the recipients see
  To: consdist@lindy.stanford.edu
and occasionally someone sends mail to that address and it goes out
to the entire list (obviously my intention is that only I be able to
mail to the list).

Someone suggested that I ask the sysadmin to change the line in
/etc/aliases to read
  consdist: whenry
and add a second alias like
  __consdist__: :/whenry/Mail/consdist-list

Then when I add the headers I would use either no To:  or To: consdist
(which now points to me instead of the list)
and
  Bcc: __consdist__
  Reply-To:consdist@lindy.stanford.edu 
     (which now points to whenry@lindy)

This sounds fine to me but before I bother the sysadmin I wanted to
check to make sure that (a) this is the best way to do it and (b)
there aren't any hidden problems awaiting me.

A related question: is this what rfc822's 
  group = phrase : [#mailbox] ";"

is for?  If so (and if you think this would be a good way for me to handle 
this), could someone please show me how to do it?  All my experiments have 
failed.

Many thanks for your help,
