I moved all my sites to a new dedicated server a few days ago and all seemed to go very smoothly except for a few bouncing emails. I assumed that was just propegation and would settle down but this morning one of the headers concerned me saying about the IP being blacklisted.
I used an online checker and sure enough, my new IP address is on 2 spam blacklists. I can only assume that a spammer was perviously using this IP before I was sold it.
I've already emailed my hosting company and am waiting for a response but wondered if anyone here can offer any advice. Should my hosting company have checked this before, or is it just bad luck? Is there a way to be removed from the blacklist or do I need to switch servers again?
Any help here would be gratefully received.
