Re: trying to figure out why mail is bouncing
So, Ben, I think I have to make changes in a few places.. help me figure this out... there's /etc/named.conf then, there's /var/named/38.232.199.hosts and /var/named/threeofus.com.hosts any idea where I should be making changes?

Re: trying to figure out why mail is bouncing
Thanks there Ben, I think I getcha... I run DNS for 199.232.38.4 and all the domains associated with it...

The /etc/hosts file has nothing to do with it. You need to have your ISP put a PTR (pointer) entry in the DNS for your IP address. Or have them delegate your IP subnet to DNS nameservers you control.

It may not be your DNS servers fault. If your ISP is not forwarding
reverse lookups to your DNS server, but trying to answer them
themselves, then that would be the problem. On your DNS server, you
should have have a reverse file (either a rev.x.x.x or db.x.x.x, or
whatever you file aming scheme is). That should have the numbers that
you have in your IP lock. In your named.conf fle, you should have a
section like this:
zone "x.x.x.in-addr.arpa" {
notify yes;
type master;
file "db.x.x.x";
};
Where x.x.x is is the network numbers that you use. The corresponding
file should have:
1 PTR mail.threeofus.com.
2 PTR server.threeofus.com.
etc. etc. etc.

When I did a lookup on the IP address, I got an NXDOMAIN error. There is apparently no reversae lookup for your mail server. Some people configure their mail servers to only accept mail from servers that can be reversed.
