RIPE NCC has been running ipv6 mail for some time, so this may be higher
than average.

Don't forget it also said:

        "this excludes messages already rejected by blacklisting and
        greylisting ... and sent to non-existent email addresses within
        the ripe.net domain"
        "Additionally, our statistics only take our primary MX system
        into account (and not email sent from the secondary MX system to
        the primary)."
