On a fresh new install of Exchange 2007 (co-existing on the same domain with an old server with Exchange 2003), the emails are not sent on Internet.
I've configured a new Exchange Mailbox on the new server (Exchange 2007)
I've configured a new send connector under Organization Configuration > Hub Transport > Send Connector tab.
But when I send emails from my new account (with outlook 2003) nothing appends : from the outlook side the email seems to be correctly sent (I can see them in the "Sent' folder). But the exchange server doesn't do anything, and I can't see any SMTP traffic on my Internet connexion.
Please Help !!!!!
