I'm playing around with ASSP and postfix on a gateway server... Basically all mail sent to the server will run to the gateway 10.0.0.1:25 (gateway.hostname.com), Hit ASSP, once processed will then be routed to localhost:10.0.0.1:25(same server postfix config handles the difference) and then postfix is setup to forward the mail out to the receiving server...
The issue I am having is that all mail routed to be sent to 10.0.0.2 (receiving server) does not get there, postfix give's me a relay not allowed error message...
Basically I want to forward all mail to the gateway once processed through to the 10.0.0.2 ip address, that server can respond if the recipient is invalid.
What do I need to change to allow this change?
