I don't quite see how this is anything to do with IPv6.

If you set up an IPv4 mail server with no reverse DNS, your mail would
be rejected by many servers, too. And there are certainly plenty of
providers who won't let you configure the reverse DNS of an IPv4 address.

Your provider assigned you an IP address with no reverse DNS, and you
set up a mail server on that IP address. Most people would say that was
unreliable even before knowing you're talking about IPv6 instead of
IPv4. <shrug>
