Lets assume a Mail is send by a user to a recipient.
As soon as an Outlook users sends an email, the Microsoft Exchange Mail Submission service takes over.
Store driver service which continuesly checks if there is any Item in Outbox folder.
Once any items is found Store Driver uses MAPI connections to connect to the user's Outbox folder and then retrieves the it from the corresponding Mailbox server.
Then the same message is converted into some Summary-Transport Neutral Encapsulation Format (S/TNEF). This format has no plain text part, and is in eight–bit binary format.
Next, the store driver places this email into the Submission Queue and moves the message from the user’s ‘Outbox’ to their ‘Sent Items’ folder.
Once the Email has reached the Submission queue, the Message Catogorizer process MailMsg object and splits it into MIME or RTF as necessary.
All conditions, Limits and Compliances are managed and checked here.
It also get catogorized whether this email belong to a Remote Destination or to an Internal network and accordingly it placed in the destination Domain of (AQE) Advance Queue Engine.
Now as per the Routing Information available with Email, its been forwarded to (AQE) Advance Queue Engine by the Routing Groups.
Here Advance Queue Engine Places this Email address to the Exchange Routing Engine which are managed by Routing Master of each Routing Group which will determining the best path for message delivery. Routing Master determine best path for an Email analysing Link Status and Cost.
Lastly SMTP creates a SMTP session with remote SMTP host. Once the connection is establised..
INFORMATION STORE retrieves the Email and convert it as required.
Now if Email is for Internal - SMTP will be used for Intra Server Message Delivery for several components like Message Journaling and Message categorization. Exchange Servers in the same Routing Group use SMTP to communicate with each other.
If its a Internet Email Delivery - SMTP is oftenly used to deliver e-mail to other exchange organizations or other messaging systems. Exchange Server 2003 can use the Virtual SMTP Server, Exchange SMTP Connectors or Routing Group Connectors to deliver messages.
