[comp.mail.sendmail] Limiting access to mail

jf@ap.co.umist.ac.uk (10/19/90)

Does anyone know how to limit access to e-mail. I don't really want to do this,
but there appear to be moves afoot to stop undergraduate students here getting access
to external mail. I would rather this happened then stopping them getting access
full stop. Does anyone know how to do this - ie. stating that you have to be in a
particular group in order not to be limited to a particular domain (it would be
umist.ac.uk for us). I'd be interested in any pointers, or in anybody who has
tried and failed. We run Sendmail 5.61, although with some modifications.
