What's keeping projesta.app from an A

Mail servers without IPv6
receive-euw1.forge.rmta.net has no AAAA record, so mail from IPv6-only servers can't reach it directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.

projesta.app Has IPv6

A (IPv4)	172.67.145.160 104.21.79.122
AAAA (IPv6)	2606:4700:3037::ac43:91a0 2606:4700:3032::6815:4f7a

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