yes
Mail servers (MX) have IPv6
No MX records, so mail goes to the domain's own address (implicit MX). It has an AAAA record.		yes
Nameservers have IPv6
No nameserver has an AAAA record — an IPv6-only resolver can't reach this domain's DNS.

What's keeping mail.ju.edu.jo from an A

  1. The certificate served over IPv6 is wrong
    The certificate served over IPv6 at 2603:1036:3000:138::5 isn't valid for mail.ju.edu.jo: ERR_TLS_CERT_ALTNAME_INVALID. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2603:1036:3000:138::5 serves the same certificate as your IPv4 address.
  2. Nameservers without IPv6
    prim-dns1.ju.edu.jo, externaldns.ju.edu.jo all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.

Browsers on dual-stack networks will usually pick IPv6 here (the "Happy Eyeballs" algorithm races both and prefers v6).
