Yes, my IP address is on a blacklist.  I knew that already.  It has been blacklisted ever since Suddenlink (now Optimum) installed it.  How do I get off?

    It depends on the blacklist. Which one are you one?

    It depends on the blacklist, If it's on the SORBS, ignore it, everyone else does. Sorbs is useless. Another blacklist simply prevents you from running a mailserver from that IP address, but doesn't impact sending mail through a legitimate mailserver, so it really does depend ON the black list you are on.
