#26 check_pop3.pl not working

[Anonymous]

The contrib section has a plugin called check_pop3.pl
which check POP3 server by authentication, but the
plugin is not generally compatible with several POP3
servers I tested.

First, not all POP3 servers return the number of
messages right after authentication. And since I dont
care how many messages are there, a simple OK or ERR
response after authentication would be sufficient.

i tried to modify the source code, but there is a loop
which I didnt figure out why. The plugin exits with
the first OK message this way
