Reverse DNS Record For My IP
Posted on 2008-11-05
I am having a central exchange environment which hosts emails for the root and child domains. All domains have a different email domain name, with only a centralized clustered Exchange server.
All my domains have their own mx records all pointing to the same static public ip address. like mail. domain1.com, mail.domain2.com etc all pointing to a single IP.
How can I create a reverse DNS record in this case as all the emails for different domains flow through the same IP.
Can I have multiple PTR record for the same IP matching all my MX records to that IP?
