Yep. I had the same problem with my Postfix sending to a Hotmail adress.
Hotmail appears to do a reverse DNS lookup on incoming connections, and
when the incoming server is not in the DNS, it will refuse the connection.
Obviously a spamblock. It went away for me when I configured Postfix to
state it's sending domain as my fully qualified domainname (I have an
account at dyndns.org).
