Usual way to configure access to server (in this case - pop3 service) is setting up firewall rules. Reverse lookup of connecting IP anyway is useless - user can configure mail client anywhere in the world. POP3 protocol don't implement any host based rules like SMTP "HELO" restrictions. If you want restrict access - only one way is allow/deny appropriate IP/Netblocks. It is firewall job.
