What's keeping verisign.com from an A

Mail servers without IPv6
mail1.verisign.com, mail2.verisign.com, mail3.verisign.com, mail4.verisign.com, mail5.verisign.com, mail6.verisign.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.
