qmail-pop3d not timing out?

[Fred Backman]

(1) If I want to change the qmail-pop3d timeout, is it correct to modify
the line

int timeout = 1200;

in qmail-popup.c and qmail-pop3d.c? If not, how do I go about?

(2) I did just that, changing it from 1200 to 30, but the timeout only
seems to work in the authentication stage, ie. before i'm actually
logged in. Once i'm logged in, i can still be idle for more than 30
secs.

Any idea what's going on? Please help.
