Any clues?
     

I don't think this is possible. However, I'd really like to do this as
well. If you ever figure this out, please share this with me and the list.
   

1. allow smtp traffic from your network to your smtp server
2. block smtp traffic from your network to other smtp servers.
3. install authentication system on smtp server.

sounds like logical solution.
or control relaying by setting ip addresses and not networks.
 

Tomas,
I'm looking for a per-user solution, not a whole mail server solution. I 
have many different groups of people on my server, in different offices, 
and only a handful (like 50 or so) need to have restrictions placed on 
who they can email to and receive mail from. I am looking for a way to 
make some users only able to send/receive mail to/from certain domains. 
It sounds simple, right?

Controlling relaying won't work for us as we use DHCP, so it would be 
very difficult to isolate these users by IP address as to whether they 
could send mail to the Internet or not. Also, that only restricts 
sending email to the Internet, not receiving mail from the Internet.
