There may be an obvious answer to this question, but I have not found it yet. I have two email messages that were sent to two different people in our company. One individual did receive the message, the other did not. I want to try to better understand why. One way that I can think of to do this is to pick apart the raw email message (we use Exchange 2003) and see if there is a possibility that the problem resides at the senders side rather than our side.
What techniques are typically use to dissect email messages and/or verify their validity. Also, what can be done on the Exchange side to understand what may have happened to undelivered email messages. I have asked our local exchange administrator, and he can't answer the question for me, so I'm looking to the community for help -- Thanks.
