OpenMR: Open Mail Relay

I have recently written a simple tool that check for Open mail relay server. I used to wrote Object Oriented Programming using Java and C++ during my Uni days. But they were like almost 10 yrs ago. But i still work on Unix shell script and Windows script host in these few years, writing system maintanance (backup, health alerts, etc) and hardening script.

This is my first time writing a program in Perl. This tool will check if the mail server of a domain is configure as an open relay. It can also query the IP address of those servers.
