If you are indeed interested in setting this with IPv6 (and ofcourse
have IPv6 ready machine/tunnel-broker), just add an entry in your DNS Zone
file with something like:
mail.wanachi.com. IN AAAA IPV6-address
(Example)
ipv6.open-systems.org. IN AAAA 3ffe:1200:3028:8655::1
And reload your DNS. Anyway, don't forget to add the MX entries if you
do set this up!!

Ok, so its been settled then? At present I am doing both A6 and AAAA
on my DNS just in case some IPv6 speaking program does not do one or
the other..
Is it safe for me to take these entries out or should I wait?

Vanilla, adj.:
Ordinary flavor, standard. See FLAVOR. When used of food,
very often does not mean that the food is flavored with vanilla
extract! For example, "vanilla-flavored won ton soup" (or simply
"vanilla won ton soup") means ordinary won ton soup, as opposed to hot
and sour won ton soup.
