Qn: How to restrict in/out emails within a domain name/internal organisation only?

Hi,

I have searched high and low for a solution to my problem but couldn't not find any. Really need help on this one.

I have a server that runs RedHat Linux 9.0. For one of the domain names, I wish to restrict email communications within that domain name only. That is, tom@domain.com could only send/receive to/from jenny@domain.com and vice-versa. If you like, I am trying to implement a closed email system for communication within an internal organisation only.

Does anyone know how to achieve this?

Many thanks in advance.

As you fail to tell what daemon you're using, and as I'm not used to work with RH, I can only
tell you that you might want to have a look at relaying (or at least preventing it).

btw: as you're posting in a security forum, I really feel I must say that RH9 is not
really secure anymore. Support stopped in April, it's August now; time to upgrade don't you think?
