A recently configured Exchange 2003 server (Windows server 2003) is sending out spam.  From looking in the queue, I can see that the mail is going out as security@(some characters)-westernunion.com.  I have added *@*-westernunion.com to the blocked senders list.  I have also verified that the server is not set for open relay.  What are some best practices and some procedures that I can use to track down the source of the email?

Thank you.
