Hi,

Unless you can find a way to keep anyone else from sending mail to this =
list,  I don't reccomend doing this.

We tried this several years ago as a way to send an email to all of our =
ISP customers at once and quickly discovered that if one (or more) =
computer on the list had a virus then everyone on the list started =
receiving virus containing email. Now, of course, we stop viruses at the =
server level before they reach the mail boxes but even so, you can see =
how problems can crop up doing a mailing list this way.

There are better ways. Someone mentioned Mailman. Also, do your students =
pop their mail? If so, do you use Qpopper as your POP3 server? If you =
do, you might look at Qpopper's bulletins feature. That is how we solved =
this problem.=20

  Subject: Simple Mailing List with Sendmail


  Hi,

  I am experimenting with a simple mailing list setup for some (15=20
  - 20) of my students, i.e. I put a line like this

  maths: user1, user2, user3, ..., /var/mail_archive/maths

  into my /etc/mail/aliases . The last entry produces a kind of=20
  archive file.

  Does anyone know an - equally simple - method to exclude/block=20
  everyone else from using this list? Of course, Sendmail users=20
  different from maths shouldn't be affected.

  Thanks and regards,

  Uli.
