Quite a few, actually. About 40% of my email comes and goes via IPv6.
Sendai, postfix, outlook, and several others all handle IPv6 without need for
any more IPv6 specific configuration than is required for IPv4.

Yes. Most of the transit providers I deal with offer ip6.arpa delegation at

providers to host that delegation.

So far I’ve had no issues exchanging mail with Google, Yahoo, or MSN (former
Hotmail) on IPv6.

True. Guess what… SSH, VNC, SMTP, IMAP, and many other things are working just
fine on IPv6.
IPv6 isn’t just the web either. IPv6 is the modern internet.
