My mail server was getting used by spammers, they were using it to send out asian porn and other things such as kitchen tools. Now I configured the mail server correctly to not send out any e-mail unless the user is local and belongs to the network. I then configured the router to deny this person's ip address which is but I have a feeling that my server maybe on a "list" somewhere as an address that will alow other spammers to send their mail. I was wondering if there was a website or anything that I could submit these addresses to warn other people that may be in the same boat. Also if anyone has any ideas on how to punish the spammers that would be cool since it's running on my personal network.
