Test remote system for unsecured mail proxies
pxytest is a command line utility to test a host for open proxies that are vulnerable to spammer abuse. It is written in perl.
Unsecured proxies currently are the most significant conduit of junk email. This is a particularly vexing problem, because open proxies, unlike open mail relays, hide the origin of the spam, making it impossible to trace. This utility tests a host to see if it is vulnerable to such abuse.
