Delivery Status Notification in Exchange 2003
Posted on 2009-05-07
Some of my users are getting a delay status notification error message when sending to a specific out of company email. I have an Exchange 2003 server and have changed the outbound delayed interval from the default on my SMTP server. But this is still happening. I use a spam service, MXLogic and when I do a lookup test I get an error message that says my reverse DNS has failed. Could this have to do with pointing my MX records to MX Logic and on the SMTP server being at a different IP?
