Query on Outlook Junk Mail

Hi

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?

Many thanks!

Hi Simon

Thanks, so basically if the messages are sent using a programme that uses MAPI (e.g. Mail Merge), there shouldn't be no problem..however, if they are using an application server then the mails would have to be routed via the IMF servers still and they will be filtered as per policy?

You say mails from MAPI have an SCL of -1: Is this because they avoid the servers with the IMF filters on them, or IMF knows that MAPI originated mail is safe and therefore assigns a -1 mark?

If someone is in a position to send spam via MAPI then you have bigger problems to worry about. Therefore as long as it using Outlook or a MAPI interface (like a Blackberry server does) then it shouldn't be a problem. MAPI are internal emails, so IMF knows they are safe. Although I may be thinking of Exchange 2007 IMF which does the -1, I think on Exchange 2003 they don't go near the IMF system.
