What's keeping flowx.chat from an A

Mail servers without IPv6
eforward1.registrar-servers.com, eforward2.registrar-servers.com, eforward3.registrar-servers.com, eforward4.registrar-servers.com, eforward5.registrar-servers.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.

flowx.chat Has IPv6

A (IPv4)	104.21.17.77 172.67.175.75
AAAA (IPv6)	2606:4700:3037::6815:114d 2606:4700:3030::ac43:af4b

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