Ugh.   M$ Outlook trying to use NetBios Name Resolution instead of DNS :(

NetBios....

Tell the client machine (or Outlook, if this is one of those things which 
Outlook tries to look after by itself, never mind how the rest of the machine 
has been configured), to resolve names by DNS, not by using NetBios.

Then it might sensibly look up the IP address of your POP3 server and send a 
TCP packet to port 110 on it....
