The message tracking service enables administrators to search for a particular 
email message or group of messages that match specified criteria, such as the 
message subject line, date and time range, envelope sender or recipient, and 
processing event (for example, whether the message was virus positive, spam 
positive, hard bounced, delivered, and so forth). Message tracking gives 
administrators a detailed view of message flow. You can also “drill down” on 
particular email messages to see message details, such as the processing events or 
the envelope and header information.
