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.
