You should be able to use the check_compat ruleset for this:
5.1.4.4. check_compat
The check_compat ruleset is passed
sender-address $| recipient-address
where $| is a metacharacter separating the
addresses. It can accept or reject mail trans
fer between these two addresses much like the
checkcompat() function.
e.g. the following
Scheck_compat
R$+ @ intranet $| $+ @ intranet $@ OK
R$+ @ intranet $| $+ $#error $@ 5.5.4 $: "553 Real domain
name required"
will allow mail from one @intranet address to another, but reject
anything else with an @intranet sender address.
Note that this ruleset is applied when the message is received, so it
won't take into account any address translations which are performed
by other rulesets.
