Check this:

http://www.postfix.org/RESTRICTION_CLASS_README.html

...on the section "Restricting what users can send mail to off-site destinations".

But in my opinion, this could be not effective, as descripted:

Quote

Note: this scheme does not authenticate the user, and therefore it can be bypassed in several ways:

By sending mail via a less restrictive mail relay host.

By sending mail as someone else who does have permission to send mail to off-site destinations.
