That means in the case of no MX record, I suggest the following algorithm: - if a domain has only A records, synthesize a MX record - if a domain has A and AAAA records, synthesize a MX record only for the A records, the AAAA records should be dropped. - if a domain has only AAAA records, do not synthesize a MX record For a MTA with ipv4 stack, this would mean no change. For a MTA with dual stack, only the ipv4 part would use synthesized MX records. A MTA with ipv6 stack only would never synthesize a MX record.
+1 (this algorithm is what I have been suggesting so of course I agree).
