What's keeping dispassionateproject.org from an A

Mail servers without IPv6
us1-smtp.messagingengine.com, us2-smtp.messagingengine.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.
