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, 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.
