What's keeping ionosqamailupsell002.com from an A

  1. www.ionosqamailupsell002.com is an alias of ssl.goentri.com, which has no IPv6
    www.ionosqamailupsell002.com is a CNAME, so it can't also have its own AAAA record. Ask whoever runs ssl.goentri.com to enable IPv6 there — or replace the alias with the A and AAAA records they give you. Why some hosts don't offer IPv6
  2. Mail servers without IPv6
    mx01.ionos.com, mx00.ionos.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.
