I am receiving the following error message from bounced emails:
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<server.mydomain.local #5.5.0 smtp;550-EarthLink does not recognize your computer (xx.xx.xx.xx) as connecting from an EarthLink connection. If this is in error, please contact technical support.>
Is this because our email server is sending mail using our internal domain name instead of our external public domain name? How would you change this? This is on Exchange 2003 with Windows DNS.
