    I have a dedicated server with a /29 block. I have certain sites using dedicated IPs. I have MX entries for mail.eachdomain.tld and the dedicated IPs are failing rDNS on some servers. Should I be setting the PTR records for all the IPs to mail.hostname.tld? Or should it work with mail.domain.tld?
     
    Solved! View solution.

    Hello, set either hostname.tld or mail.domain.tld, don't use mail.hostname.tld as it is an incorrect PTR entry.
    After you set the correct PTR, you have to wait for 2-12 hours till the entry gets updated on the server.
