Message Trace
If you have ever tried to read the Received headers of an email to try and locate a bottleneck, or to confirm it's sender then you will understand how tricky it can be converting time zones and working out all the details contained within the headers. The MailCOPA email client contains a built in message trace. Just select the message trace option and see all the servers that the email passed through on it's route to you, and the length of time the message took to get between each server.
