pop3/tcp server failing (looping), service terminated

[Ilya Palagin]

Hi,

Doing stupid experiments with my server (Mandrake 7.0, qpopper 4.0.3) I 
found an easy way to shut it down from any client, sending a bunch of 
requests by clicking (3 clicks per sec) on GetMsg button (in my case 
it's Mozilla). inetd terminates qpopper with the message:

inetd[379]: pop3/tcp server failing (looping), service terminated

How can I prevent a malicious user from clicking so fast? :-)

Thanks,
Ilya.
