DNS, Ipv4 ipv6... such a boooooring SHIT!
I finaly know why ipv666 adaptation is so slow: they made the (unpaid) software migration to it a pain in the ass.Most pro'lly the administrative migration process isn't any better.
probably not yet all done with ipv6 + relay, but most of it.
btw, i've heard that one should use braces when having ipv6 addresses in URLs like that:
smtp://foo:bar@[::127:0:0:1]:666
so this is how one will be able to relay through an ipv6 host without dns.
