What's keeping aster.investments from an A

Mail servers without IPv6
mx2-hosting.jellyfish.systems, mx3-hosting.jellyfish.systems, mx1-hosting.jellyfish.systems 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.
