Sure, but not having the ability to access smtp.live.com and
pop3.live.com would imply firewall rules that prevent US IPs from
accessing them. Clearly, though, those two servers have IP addresses
in Microsoft's network (65.55.172.254 and 65.55.172.253) and I can't
think of anything that non-US clients would do that is different from
what US clients would do, so it's not like there would be a
functionality change.
