IP addresses are added to the MAPS RSS because they are insecure ("open relay") email servers that have transmitted spam to our users. Spammers hunt for and abuse these servers to try to cover their tracks, because they know their spam is unwelcome and unwanted. Many email administrators choose to use our list to refuse mail from those servers, until they are fixed to stop relaying spam to our users.

You need to contact your ISP (the company you pay for internet access). Write them or call them and tell them that you're having trouble with your email, explain to them that you received this error message, and ask them to visit our web site. If the server is owned by your school or employer, then contact the folks that run the server and explain the same thing to them.

We know that email is important to you, and we want to help your ISP resolve the problem of your mail bouncing. Correcting this problem is usually a very simple process, involving your ISP changing a few lines of one configuration file, or ticking a checkbox on a configuration form.
