What's keeping ledgerwalletsecurityupdate.com from an A

Mail servers without IPv6
_dc-mx.5a98b1a238f8.ledgerwalletsecurityupdate.com 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.
