I have an SBS2011 server running the latest version of Exchange. My current setup is an MX record that sends email to IP 126.96.36.199 and a subsequent PTR record that goes in reverse.
I have setup another two domains as authorative domains and have been using SBS POP3 connector to use them but due to a sudden increase of users for those domains, I would like to make them “exchange complliant”.
My idea is to change the MX records for each domain to 188.8.131.52 and use the webhost as a backup with a higher priority to ensure some redundancy. How would I go about setting up the PTR for the new domains though?
From my understanding you can only have one PTR per IP.
Primary domain: MX record ->184.108.40.206 PTR-> domainname ->220.127.116.11 (which works fine)
secondary domain: MX record->18.104.22.168 PTR->?
