What exactly are you using the address pop.domianname.com for?  Is so
users can connect to the server and retrieve their mail? or will they
also be sending mail to pop.domainname.com.  

If people will only be using pop.domainname.com to retrieve mail, then
you do not need to setup an MX record for it.  MX records are only for 
machine that will receieve mail.

Now, if pop.domainname.com is not available, have you tried to resolve
in on your DNS server?  

nslookup pop.domianname.com <dnsserver is is defined on>, does that 
work?  Generally if people can not resolve a domain name it happens
because

o name is not defined right in DNS
o it has to propagated out yet

Hope that helps.
 
: Can anyone shed some light on this for me. The cobalt manual is not very
: enlightening.

I highly recommend the O'Reily DNS and Bind book for DNS issues.
