Hello! I recently upgraded my Exchange 5.5 to 2003 by joining existing site
of the 5.5. Since then I moved all my mailboxes to 2003. My 5.5 is still
in place and all external mail is still being routed to 5.5. Here is what i
think is a problem that I noticed recently. When I send out mail to
multiple external recipients, and then I go to the message tracking center
in 2003, I can see that the email is being transfered from 2003 SMTP to 5.5
MTA for delivery. Why does this happen? Shouldn't the 2003 SMPT make the
delivery itself? Please advise.
Thank You
