We are using Exchange 2003 SP2 and Outlook 2003/2007 clients. We have IMF enabled and running on the Exchange gateways that connect with our 3rd party SMTP relays. We are running a multi-domain AD forest and one Exchange org.
One of our departments wants to send some mails to a number of internal users and we want to ensure these don't get caught in the Outlook Junk Mail.
Could someone just confirm that it's not possible for internally originated mail (i.e messages sent from within the same Exchange org) to be classed as Junk? Or is it?
If so, is there any way to 'whitelist' our mail domain?
Also, does any of this behaviour change with Exchange 2007?
