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.

Your MX record is not involved in sending mail unless you are using the mx mechanism in your SPF record.

Make sure the new sending IP has a PTR record that matches the A record of your new server, and modify your sending domain(s) SPF record(s) to include the new sending IP.

I know the mx record technically is for recieving mail.  But most spam filters are looking at your sending ip and name and matching them up to your known mx record to see if they match.  

We are not using spf records.  Our old 2003 server has not had an issue being marked as spam but when we use the 2010 within a few hrs we are marked as spam

No they are not.

We are not using spf records.
That's not recommended regardless of this issue, and one thing receiving servers DO do is check SPF and some will not accept mail without one. Create the A and PTR records for your new sending server which is most likely the source of this problem and then create an SPF record for each sending domain.

E.g. assuming your sending IP's are 1.2.3.4 an 1.2.3.5
"v=spf1 ip4:1.2.3.4 ip4:1.2.3.5 -all"
