I was wondering if anyone had a good source for the path a message flows through for Exchange 2003. I am very familiar with other e-mail systems and there has been times when a corrupt or overloaded system can bring the e-mail server to its knees. The solution has been to clear the file(s) from the queue in its appropriate folder location. I've read through various documentations for Exchange 2003, but haven't found one that contains a "flowchart" for the e-mails going to or coming from the Internet. Thanks.
