What's keeping resolvingservices.digital from an A

Mail servers without IPv6
_dc-mx.498c9b390718.resolvingservices.digital 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.
