So please explain step by step how to configure postfix to forward only inbound mail to exchange.

Yes only handles incoming email outbound goes straight from exchange server out to external.
relay_domains=<<domain name>> what domain name
I have a windows server 2003 domain zentura.local
My external MX record is mail.zentuar.com
My exchange has two recipient policy default on zentuar.local and one I had zentuar.com
And will postfix accept inbound mail or what must I add on postfix to accept mail from external.
Please explain.
it would be zentuar.com. You put in that list whatever is after the @ in the email.
mail.zentuar.com should be pointed to the public IP used for the postfix server. Oh, and check that inet_interfaces is set to all in main.cf as well because by default it only listens on the loopback interface. This will ensure email can get to the postfix server and the other config options I gave earlier will ensure it gets forwarded to exchange properly.
yes. I'm not a 100%, but you might even be able to leave the relay_domains part off the config. I can't remember for sure, but having it in there won't hurt.
however, one change, its probably better to do this for relay_domains
relay_domains=$mydestinati
This way it will relay for whatever is listed in the mydestination parameter as well which it does by default.

so it ONLY handles incoming email? outbound goes straight from the exchange server or relays back to the postfix server?
if it only handles incoming, its easy, just add this to the main.cf
relayhost=<<fqdn or IP of exchange>>
relay_domains=<<domain name>>
if exchange relays back, then you'll add this instead
relay_domains=<<domain name>>
my_networks=<<what is there now>>,<<ip of exchange>>
then in the transport file you add this
<<domain name>>: <<fqdn or IP of exchange>>
then delete the old transport.db and restart postfix. It should auto-recreate the transport hash file for you then. To do it manually, you use postmap.
