Solving cases of mistaken identity

More and more spam filters are starting to crack down on incorrectly name servers. There are even blocking lists specifically for incorrectly named servers!

			Changing the name

Fixing this is relatively straight forward, simply follow the instructions below;

1. Open up Exchange System Manager
    
2. Drill down to "your server" > Protocols > SMTP > (Right Click) Default SMTP Server > Properties
   
   
    
3. Click on the "Delivery" tab
   
    
4. Click on the "Advanced" button
   
    
5. Here, you can see the incorrect entry "server-1.domain.local"
   
    
6. This should be changed to whatever your server is known as in the real world - in this case, server.domain.com
   
    
7. Click OK all the way out, and you are done - the change should be immediate.

			Final notes

In this example, our servers full external name was server.domain.com - the standard is usually something like mail.domain.com, it isn't important what the name is, as long as what you have in the FQDN field is accessible from the outside world. Also, forget about the "Check DNS" button, it is not important.
