One of the guys I had my hosting with wasnt set up correctly, the server was an open relay and there were a few other problems. Within a day my accounts where hacked and used for mass mailing phishing and scam emails. We sorted this out and moved to a new server. The domains are blacklisted. on 11 lists out of 110. Now does this means I would be spam box (or not even delivered) every time to all address's? Does this mean its just the domains or domains AND IP of server? Would I need to switch host again?
