Hi! I finished the Patch forqmail-pop3d which doesn't allow more then xx logins every yy seconds. (As some of you may know from GMX.net) If you log in more often then eg. 10 times in 5 minutes you get an error message which says, that you have to wait xx minutes until relogin. Thats quite good against pop3 bruteforcing, I think !
If anybody is interested in how including this feature, please write me ! Thanks, knom.
