That means the pressure is greater or less for different services. Email by its nature lets you put enormous numbers of users or domains on a handful or IPs, so the incentive to switch to IPv6 is minimal. Also, some providers including Gmail require better authentication over IPv6. If you want people to accept your v6 mail, you really need to put DKIM signatures on it. I don't find that to be a problem but I have been surprised to find how many places say it's working fine and we don't want to change anything because it might break. R's, John
