postfix and NAT routing
(Click here to view the original thread with full colors/images)
Posted by: BooRadley
I've offered to help a friend of mine with her website. Her setup involves sevral machines, mostly running Linux, behind a router that handles NAT routing. She has one legit IP address, and on the other side several non-routable addresses. The one legit IP doesn't reverse-lookup to her domain name, either.
I'm trying to set up the mail server now. I'm going with postfix because it's supposed to be easy, but I'm having a problem with outbound mail. It never shows up at the destination. Before I changed $mynetworks and $mydomain, it wouldn't even attempt to send, saying that it won't relay, but now it says it sends but it never shows up.
mynetworks = 68.209.157.0/24, 68.48.26.0/22
mydestination = $myhostname, localhost.$mydomain $mydomain
I also tried adding:
relay_domains = $mydestination
But nothing seems to help. I'm pretty sure the problem has to do with reverse-ip lookups on the recieving end, but I'm not sure.
Does anyone have any experience with this, or any idea what the problem is?
