problem with postfix as smarthost for exchange 2003

Post by mikectd2002 » 2009/04/02 16:13:12

I have my exchange 2003 server configured to use postfix as a smarthost however some sites (yahoo as example) mark the email as spam. What do I need to change to fix this problem.

Header info from my test to yahoo:
