What's keeping sterling-dash.com from an A

Mail servers without IPv6
mx1-usg2.ppe-hosted.com, mx2-usg2.ppe-hosted.com, mx3-usg2.ppe-hosted.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.
