A small application built to test the performance of a pop3 authentication system using a lot of concurrent connections. It can also be used to try lots of password against a pop3 server. It is capable of using up to 1024 (or more using multiple processes). However with this amount it is capable or reducing internet connections to a crawl and also greatly increasing the load on the server.

Options currently supported are

Usage: ./brute-pop3.exe [ options ] <host> <user>

        -d <n>     delay between connections default: 2

        -h         Print this stuff

        -m <n>     Use n number of connections default: 3

        -p <port>  use a different port number default: 110

        -u         Instead of reading password use a constant

                   password and brute users

        -s <n>     dump stats every n seconds default: 60

        -t <n>     set timeout to n seconds default: 30

        -v         verbose mode repeat to increase
