Outllok cmmunication between Exchange server 2007

what my understanding of mail flow in Exchnage server 2007 is,

When a message is placed in the sender’s Outbox,
the Microsoft Exchange Mail Submission service alerts the store driver,
which retrieves the message from the sender’s Outbox.
The store driver then places the message into the Submission queue on a Hub Transport server,
this can be any hub transport server in the same Active Directory site as the mailbox from which the message was retrieved.

The Categorizer then pick up one message at a time from the Submission queue and places it in a delivery queue.
If the recipient resides in a local mailbox server it is placed in a mailbox delivery queue,
 the delivery queue delivers the message to a local mailbox by using the store driver.
If the recipient is on a remote server the a remote delivery queue delivers the message through a Send connector.

===============================================================================
 Please clarify the following points.

, The Microsoft Exchange Mail Submission service is always running and it should be alerted for mails are comming
into the sender's outbox( usually the user can't see this delay .) and mail submission service alerts the "store driver" .

here we can say that the mail submission service is running in a Mailbox server ,

 Q:1 )  what about the store driver, Does it also resides in mailbox server or hub transport server ??

 microsoft Exchange mail submission service --( Submits messages from the Mailbox server to the Hub Transport servers.) , this means the service its self put the messge into hub transport server with the help  store driver ( where the submission queue resides) ?

 Q:2)   Is there any sense of thinking that hub transport server will come and fetch the mails from mailbox server and copied into submission queue ?

   It is claer that categorizer, submision queue ,delivery queue resides in hub transport server, is it correct ??



 "the delivery queue delivers the message to a local mailbox by using the store driver----- i get confused here with "store driver" , please expalin in which server it resides( HUB/ MAIL BOX server ) ???? how to verify it ?

1.) The store driver is running on the hub transport server. The mail submission service notifies the store driver on the hub transport server with a message ready for submission.

2.) No, they hub transport server must be notified. If the mail submission service is not running, messages will never leave the Outbox.

Don't confuse the store driver with store.exe which is the Information Store service. The store driver is only present on the hub transport role.
