ddns-update-style none;

This means that the dhcp server should not try to update the specified
DNS server with host and IP address details for the clients. Typically
this will be  your internal dns server and it is the internal IP
address, say

It would be a very odd setup if the ISP were to allow you to make DNS
entries into the ISP's DNS server. There could be many PCs located
behind NAT routers that all use the same IP addresses, such as

The ISP only sees connections with the source IP address being the
public IP address on your ADSL router. They do not know or care what IP
address range you use behind the router. They cannot directly initiate a 
connection to those clients.

If you can ping the pop server and you can telnet to the pop3 port on
that server from the PC in question, then you have clear communication
to that service. So now it looks like a mail client configuration issue
to me.

I hope this helps.
