Exchange 2007 relay mail

We are using Exchange 2007 SP1. A monitor server which hasn't put its IP in the Exchange Anti-spam Hub Transport can send out a email using the same domain name. In addition, the email address used in the monitor server doesn't exist in the Exchange server. Is that normal or do I overlook some configuration on the Exchange Server ? (ie. montiorserver@abc.com can send to helpdesk@abc.com)

That is normal.  As long as the recipient is on the server (the server is not relaying the message to an external domain) messages can be sent to the email server without any authentication (anonymously).

The sender address can be any email address you want.  It does not need to be valid - the server will have recipient it recognizes and it will deliver the message.

It's a normal behavior. You can send an email internal or to your accepted domains without a different connector. If you try to send to an external domain you will need an dedicated connector an proper permissions.
