MX Offenders

Mostly for fun. I host my own e-mail server and noticed one day that there were a TON of login attempts made to the server. I decided (also for fun) to write some software to watch the logs and auto-ban these failed attempts. Yes, I know this is what software like Fail2Ban is for, but you know...fun.

I also thought that if anyone else could make use of my IP ban list, then why not make it available?
