the 47.53.. address is only the current address of my home laptop. The server we are talking about is a VPS in a datacentre. And reverse lookup of the IPv4 and v6 addresses of that server already both return the domain name "example.com", which as I said is not exactly the same as the value of $myhostname, which is "a.mx.example.com" and makes me suspect that may be the problem, rather than delays in dns propagation.
by "turning ipv6 off" I assume you mean changing "inet_protocols = ipv6, ipv4" to "inet_protocols = ipv4" and commenting out "smtp_address_preference = ipv6", I guess?
