Hello Gentlemen,

Apologies if my doubt has been answered somewhere else, but I was not able to find at google any solutions. I think that maybe this is not a Slackware question, but since I'm installing postfix on Slackware, I thought here someone could find me an answer.

I have a server with two interfaces with real IP's, from different networks ranges. The eth2 connects the server to the company's router. The eth3 has a real IP address from the same range of real IP's that I can use on my department. The problem is that only the IP of eth3 has DNS reverse lookup available, and my domain register also points to that IP. The messages from Postfix reach their destination as if they were send from IP at eth2. I just can't make dns reverse lookups available for eth2, corporate rules.

Is there a way to bind postfix output connections in the same way we can use the inet_interfaces for the entry connections? Is there a way of defining a range of ephemeral output ports?
