Exchange 2010 EHLO response - internal domain name

Hi,
Our mail server is getting tagged as a spam host because of this:
220 BLADE1.XXXX.local Microsoft ESMTP MAIL Service ready at Mon, 11 Jan 2010
10:46:30 -0500
Our send connectors FQDN lists:
mail.xxxxxxxx.com
Could anyone guess why the server is returning the internal host name of the server instead of the specified FQDN response above?

I was able to change the FQDN on the default send connector to the external host name by disabling exchange server authentication and things are working fine now.
