What's keeping useinsider.com from an A

Mail servers without IPv6
primary.emea.email.fireeyecloud.com, alt1.emea.email.fireeyecloud.com, alt2.emea.email.fireeyecloud.com, alt3.emea.email.fireeyecloud.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.
