What do I do if I am NOT a Hypercon user and I have gotten a message saying that my emails are being blocked by a blacklist?
You need to reference the information we have listed below, and if your ISP’s mail server is listed then email their technical support and let them know which rejection list they are on. They should be able to resolve the problem within 48 hours. If your email if was blocked because you are attempting to run your own personal mail server in Internet address space which is not allowed for that use, you can contact the administrator of the list you are on, but they will most likely not remove your server from that list unless your upstream ISP asks them to allow your address space to house a personal mail server.
