Hello EEs..I would like to know exactly how a email message flows from the time you hit send in a MS Exchange 2003 server environment using Outlook mail. The path the message takes from senders outbox to recipients inbox.

Web sites are great, however, a laymans term flow will be great too.

    Internal, external?
    The message is sent to the server, then delivered. For internal email it is a three hop process - Outlook, Server, Message Store. Then Outlook pulls it in.

    If you have message tracking enabled then it will show you the full path of the messages, with external messages being delivered to the store.

    Yes thanks. I was looking for more of teh internal process involving MTA stacks, SA and suck. Sorry if I did not specify exactly. This would be for internal mail and external mail.

    Its all explained in the technical reference guide. There is no laymans terms - there is the technical version or nothing else.
