What's keeping teamviewer.com from an A

Mail servers without IPv6
de-smtp-inbound-2.mimecast.com, de-smtp-inbound-1.mimecast.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.
