Depending on how the rest of your system is configured, I would think it
preferable to just close tcp/110 with local firewall rules.

Actually, if you don't want public (remote) POP3 access the port should be
firewalled off *anyway*.

This way you open yourself to more flexibility in the future for (random
example) perhaps splitting the web and mail servers to different machines
where "localhost" no longer has the same, special meaning.


Just one opinion ...
