I have an SBS2011 server running the latest version of Exchange. My current setup is an MX record that sends email to IP 18.104.22.168 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 22.214.171.124 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 ->126.96.36.199 PTR-> domainname ->188.8.131.52 (which works fine)
secondary domain: MX record->184.108.40.206 PTR->?
