What's keeping whatsapp.com from an A

Mail servers without IPv6
mx0a-00082601.pphosted.com, mxa-00082601.gslb.pphosted.com, mx0b-00082601.pphosted.com, mxb-00082601.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.
