Hopefully someone can help me with this. I provide hosting for multiple domains. Until now I have not had to worry about having multiple ptr records for multiple domains. Now I have one client for whom I am the dns and email provider that needs a proper ptr record in order to send bulk (solicited, receipts) to hotmail/msn which is being rejected as spam because I have no ptr for that domain.
All of the dns servers are windows servers. They would have their own non-public facing dns on their domain controllers. How does someone in my situation make records for multiple domains to one ip?
