I foresee some company setting up an IPv6 to IPv4 e-mail relay for
individuals or other companies that only have IPv6 addresses.
For an IPv4-only receiving system, would this appear as an e-mail from
test(_at_)ipv6(_dot_)l(_dot_)google(_dot_)com (even though it comes over the
IPv4 link)? At
that point, would it make sense to accept the message?
