What's keeping amazonregistration.support from an A

Mail servers without IPv6
_dc-mx.4d79ab666c34.amazonregistration.support has no AAAA record, so mail from IPv6-only servers can't reach it directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
