Best practice for sending SMTP mail using outlook 2007 and exchange 2007 with an outsourced smtp provider
Posted on 2008-10-25
Current set up is a s follows:
Exchange 2007 "mydomain.com" (with smtp send connector under OC hub transport but no reverse dns or MX)
Outlook 2007 clients
Client machines have an outlook setup using the exchange 2007 server but they also have a
smtp mail account to their outsourced smtp mail provider. The smtp account is set as defualt.
I would like to be able to use the exchange as default so all internal mail does not have to go across the internet as it is in the currnt setup. However when doing so the Exchange server sends the mail and most bounce back failling DNS reverse look up.
What happens is i remove the Hub transport smtp connector and set the outlook clients to use the exchange as default.
Since i dont want the exchange server to send mail to anything other than mydomain.com how do i go about acomplishing this ?
