mail server name resolution problem

We have a single windows 2000 server which is providing our dhcp and dns services. (well it is now, as we have just changed this over from our router providing this). Each client collects ther mail directly via a POP3 connection. Most things work OK, but for some reason we cannot use our mail server name ie mail.mailserver.net in our mail server settings. We can however use the IP address. I presume this is a DNS problem, but don't know where to start resolving this issue. If this does not work, maybe there is something else that also will not resolve correctly.
Anyone got any ideas?

There would need to be an external DNS Host (A) record for mail.mailserver.net that points to the IP address that you are using. If the server is internal there would also have to be a host record for mail.mailserver.net. Do you have the correct forwarders setup in your DNS? If not, you will need to put your ISP's DNS server IP addresses in the Forwarders section of the properties of the DNS server. Hope this helps.

We do have the forwarders set up OK, to point to our ISP DNS. The mail server in question is an external one. The strange thing is that I can resolve other mail servers from this network, and we can also ping them all. Why is it just this mail server that cannot be resolved. I thought that the idea of having forwarders set up was that anything that could not be resolved locally would be forwarded to our external DNS, ie the ISP DNS declared in the forwarders.

Does the mail server address resolve to the IP address that you have? You can try to resolve the name by using a website such as www.dnsstuff.com.

Sorry to sound dumb, but our mail server is actually situated at our ISP. The name we use is of the form mail.domainname.co.uk. I have run this on DNSSTUFF but it says that name does not have an NS record.
We can resolve our actual domain name, but did not expect that our mail server name would be suitable for any reports on DNSSTUFF. I have also run DNSSTUFF for a different mail server which I know is working just fine, and this produces the same result, ie no NS record.
