Jack,
Thanks a lot for helping the clueless. Sorry I did not describe my situation
more clearly.
We've got RedHat6.2 running on our network. Our smtp (sendmail) and pop
(ipop3d?) server, which is outside our firewall, is working fine, sending and
receiving mail from the Internet outside for all existing users.
I was wondering if I could add new users but with email accounts that can
only send and receive from within the 'firewalled' area, without affecting
existing accounts.
I thought of setting up another mail server inside the firewalled area for
internal email but is that the best/easiest way? Would existing users have
to be defined then on both servers, and wouldn't that be rather awkward
having
them deal with two servers? Or is there a way to just create new accounts on
the existing server but restrict them some way to 'internal' use?
Any help/suggestions/tips will be much appreciated. If this is documented
somewhere, could someone point me where to look or what keywords to look for?
Thanks,
Rey
