Please post the following again as what may seem correct could have a slight mistake
Code:
cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain mx
dig yourdomain any
host `hostname` <- note backticks and not single quotes (copy 'n' paste)

Near as I can tell, the DNS is set up correctly, it's just not returning the correct IP addresses.
Let's see the output again from the commands I asked you to run in pots #33. I assume you mean you've updated your CentOS box to 5.4?

Truth be told, I don't know. I SSH in and do "yum update" every so often. There were a whole bunch of updates so I guess it's quite possible.

mail.baerconsult.com has address 75.150.206.10
The reason you're gtting the wrong IP address is because you have the public IP in your DNS A record instead of the LAN IP. You also ran the following connad incorrectly:

Code:
host `hostname`  <-- use that exactly and don't change it and use backticks not single quotes

^^That's why I thought I ran it incorrectly.

My A record:

$TTL 86400

@       IN      SOA     10.0.0.10.      admin.baerconsult.com. (

                        7200            ; Retry
                        864000          ; Expire
                        86400           ; Min TTL

mail	IN	A	10.0.0.10
That, to my knowledge, hasn't been changed and was originally working up until at least the update.

That's a very dangerous thing to do on a production mail server, you should check what you're updating on your server before you commit the transactions and never update blindly.

That's why you should run it as specified, it tells you there's a DNS problem.

Obviously that's not what's being picked up by your DNS server and it's also incorrect, an A record should always be an IP address and in this case the LAN IP of your server - change it and restart your DNS server and try again.

So far that hasn't changed the results of my dig commands or host commands.
