Trying to build our new exchange 2010 server, with an existing 2003 server. When we create the internet send connector. Mail sends out of it nicely. But it does not use the public ip of our mx record, rather it uses the generic public ip address (they are differnet). And it uses the fqdn of our server rather then the name of the mx record. And thus we are marked as spam. How can I force it to come from (or at least look like it comes from) the ip and dns name of our mx record so it does not get blocked as spam.
