I have an Exchange Server 2003 SP2 installed on a Windows 2003 St. SP2.A client called me because I was sent emails and I do not have arrived, or it seemed. I have gone to monitor messages and if you've entered, but in this: Message Submitted to Categorizer Exactly the message is: SMTP: Message Submitted to Advanced Queuing SMTP: Started Message Submission to Advanced Queuing SMTP: Message Submitted to Categorizer and not sent me an NDR or anything. I have been reviewing documents from Microsoft but I can not recover these emails. The configuration like this at this link: http://www.johnkellett.co.uk/index.php/2006/07/05/message-submitted-to-categorizer-when-forwarding-mail-on-exchange-server/ How can recover these emails?. Thank you.
