What's keeping onetrust.com from an A

Mail servers without IPv6
mxa-0085c101.gslb.pphosted.com, mxb-0085c101.gslb.pphosted.com have no AAAA record, so mail from IPv6-only servers can't reach them directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
