It is possible, depend on the software on both server and client side. For example, you may change your POP3 server port in Microsoft Internet Mail, at the menu Mail/Options/Server/Advanced Settings.

If you cannot change the port on the server (and you didn't say why not) then your only other alternative would be to run some type of TCP mapping daemon or service on port 80 of your POP machine that would redirect the incoming requests to port 110.  I've seen a number of perl scripts (like one called TCP-MAPPER/TCP-RELAY) as well as some generic tcp/ip mapping servers.  Even a proxy server might be able to do this.  

This seems like the long way around, how about reconfiguring your LAN/firewall to allow port 110 access?
