restricted relaying

["E.Colanski" <ecol@ibud.vr9.com>]

Hi!
How to set up in zmailer 2.99.51, that my gateway accept messages from
ONE given IP in internet in two cases:
-when sender is from my domain, no matter of receiver
-when receiver is from my domain, no matter of sender

Setting in smtp-policy.dat
x.x.x.x/32        relaycustnet +
causes relaying all post from this host with no matter of sender and
receiver addresses

Thanks in advance
