Exchange email - external adress shown

Hello! I really need some assistance here!
I have set up this new exchange 2010 server and some of our emails are bouncing cause it looks like they are send from our local domain adress (we dont have certificate on this one). I want my adress to be like on our 2003 sever!

What is wrong in the Exchange 2010 one? (its mail1)
Did this test on http://www.mtgsy.net/dns/utilities.php

There's a setting on your send and receive connectors in Exchange that determines what is shown as the Server's name when another server or client connects to it. You can change this to match your External domain name fairly easily. If you open your send connector's properties screen (Organization Configuration\Hub Transport\Send Connectors in the EMC) the tab that opens up will have an option that says "Specify the FQDN this connector will provide..."
Enter the external name for your mail server in the text box below that. Do the same for your receive connector (Server Configuration\Hub Transport\Send connectors)

do you mean you want to change it from mail.domain.com to mail1.domain.com

in the Server area EMC go to the Hub Transport.  In the Receive connector change the name to be mail1.domain.com

Also, in the Organization level check your Send connector and you may also need to change it to mail1.domain.com also

Lastly, make sure your reverse DNS is setup properly.  You will normally need to request your ISP to create the reverse DNS records for you.

Thank you very much. I got a error when trying to set the FQDN on one of the recive-connectors though - Default EMAIL. (I have 2, one is called Client EMAIL and och Default EMAIL.)

Microsoft Exchange Error

The following error(s) occurred while saving changes:

Set-ReceiveConnector
Failed
Error:
If the AuthMechanism attribute on a Receive connector contains the value ExchangeServer, you must set the FQDN parameter on the Receive connector to one of the following values: the FQDN of the transport server "EMAIL.domain.local", the NetBIOS name of the transport server "EMAIL", or $null.

Go to the Authentication tab on the properties of that connector and remove the checkbox next to Exchange Server Authentication. Realistically, only Transport Layer Security (TLS) needs to be checked there.
