unable to ping incoming pop3 mail server by name on domain

Hi,

I'm unable to ping the incoming pop3 mail server by name. It resolves to the ip address without any problems. The mail server is hosted externally. (mail.mydomainname.com).
 I have no issues resolving the name to ip on the outgoing server.

Your help is much appreciated.

Does your firewall allow ICMP messages outbound and their replies back in?

Yes - it does as I have no issues pinging the outgoing smtp server details. I am not able to resolve the Incoming mail server by name.

--> It resolves to the ip address without any problems.

I took this to mean that the name resolved to IP address.

O.K., if you can't resolve the host name to an IP address.  Then someplace it is not in DNS, or at least the correct DNS server.

Are you hosting your own DNS server internally?  Or do you rely on external DNS?  If you rely on external DNS, who hosts it and maintains it?

We host our own DNS server. I have forwarders pointing to the DNS servers of my ISP as well.

Have verified that the host name for your pop3 server is correctly defined in the proper zone within your DNS server?

It does not let me add an A record in DNS for mail.mydomainname.com. It says unable to create record - refused.

Is your DNS server the authoritative server for the domain "mydomainname.com"?

No error codes in EV. I am able to manually create A records - I get the error only when trying to create one for mail.mydomainname.com.
