What's keeping unblocked2.download from an A

The certificate served over IPv6 is wrong
The certificate served over IPv6 at 2600:1900:4001:96e:8000:1:937c:ac4a isn't valid for unblocked2.download: DEPTH_ZERO_SELF_SIGNED_CERT. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2600:1900:4001:96e:8000:1:937c:ac4a serves the same certificate as your IPv4 address.
Mail servers without IPv6
mx2.csof.net, mx1.csof.net 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.
