Hmm.
Could be easy to achieve if the users that have access and those that
don't are on different subnets, you just set:
host_accept_relay = 192.168.10.0/24
Where 192.168.10.0 is the network that you trust to send off-net messages
that are not covered by either local_domains or relay_domains.
Any other hosts wanting to send mail will be allowed to send mail only
for the domains you have in local_domains/relay_domains and not external
addresses.
If you have only a small number of users that you want to be able
to relay, you could put these into a file:
host_accept_relay = /some/list/of/good/hosts
Otherwise if this is not possible to do it on IP address, you will need
some way to lookup the user, and possibly with a system filter which
checks which user and the recipient domain and where they are not listed,
it does a "fail"....
