How to prevent some users to send/receive emails to the Internet

I have an ims-5.1, and I want to prevent that some specific users can send and receive emails to the Internet (so they can only send emails to other users on the server).

I'm trying to do this without using differents domains

Any idea how to do this ?

thanks a lot for the answers

You'll want to look at the orig_send_access mapping. The format is

!

! src-channel|from-address|dst-channel|to-address

!

For example

tcp_intranet|Juan@domain.net|tcp_local|* $NYou$ are$ not$ authorized

You could reverse that logic if wanted to allow only a few users, you'd put entries for them with a $Y and then a default policy of deny.

Keep in mind that if you are going to be doing more than 20 or so entries you'll want to do a callout to the general db and put the names in there. For performance reasons.
