    Hi Guys
    It has been suggested to me that I need to create IPV6 DNS records.

    I think that this is some of the reason why DKIM and PTR are failing, as it was suggested that some traffic could be being pushed to my IPV6 address, and there is nothing there!

    Could it be as simple as creating a PTR record, that anything coming over IPV6 forwards to IPV4 MX?

    A PTR is a reverse record for an IP, it dies not forward traffic.

    If you dont want to handle email tryffic by IPv6, then set inet_protocols to ipv4 in postfix main,cf so postfix will not listen on IPv6 and all mail traffic is handled by IPv4.

    Thanks Till, but if I wanted to go IPV6, then do I just re create all A records, but include the 6 address instead of the 4?

    In this case you Create A records for ipv4 and additional AAAA Records for IPv6.
