DNS ERROR resolving MX

[chris Fergus]

To Rsharpe Thanks for replying. I didn't relize you had replied, a I never got the email notice that you had replied.

The exact error message I'm getting is the following:

DNS ERROR resolving S1.my.domain.com
It is suggested that the hostname be resolved via DNS
Change hostname [Yes]

So I attempt to resolve it.

DNS ERROR resolving S1.my.domain.com
It is suggested that the hostname be resolved via DNS
Change hostname [Yes] y

Please enter the logical hostname for this host [S1.my.domain.com]

To verify the logical hostname I run "zmhostname" command, which returned: S1.my.domain.com. So I enter that as the hostname, but get caught in a loop.

Please enter the logical hostname for this host [S1.my.domain.com] S1.my.domain.com

No results returned for A lookup of S1.my.domain.com
Checked namserver:
              192.168.130.1 <----(S2)namserver/firewall

I even tried the physical hostname with the same results.


I ran the dig MX command again and it no longer finds the MX.

I may have forgotton to change the serial number of the db.external zone file when a made my last change to it; could that be part of the problem?

The db.external has the an A record for the physical machinmame (S1) and the IP.address.of. server that looks like the following:

S1           A       ip.address.of.server

While the db.local has the fully qualified name.

last octet                PTR        S1.my.domain.com

This is really frustrating

This thread is almost four years old, you should not have posted your question here but in a new thread with a complete description of your problem and what you've tried to resolve it. As you have posted it, did you read the thread? The answer is in here and all over the forums if you search, try setting up a Split DNS and a correct /etc/hosts file.
