Setting Exchange SCL from MailScanner

[Duncan, Brian M.]

I already replied to you directly.

Figured I would reply to the list if anyone else was looking to do the same.

>From everything I could find before, the way MS exchange and IMF works is that the SCL value that Exchange acts on is an extended MS attribute that is added to the message.  It does NOT act upon the X-Header alone.  At least I could NEVER get Exchange to act on ANY x-header I sent with a message..  At the time I was experimenting with this, I also found a way to add to the Outlook view a tab that would show SCL values of messages.  Any of the X-headers I added, never seemed to effect this.

This means that you should not be able to force Exchange to put something in the Junkmail folder by adding an X-Header. (I know you can with rules and stuff, but I mean by using SCL x-headers)

We are doing this now, but only by using a product that sits on the Exchange servers called smtptracker.  http://smtptracker.com  It was like 25.00 for the product.  They even sell the source code..  We have a few servers that all Exchange mail routes through for multiple locations.  So we have it loaded on each. (It's not loaded on each users Echange server)

Any messages that fail MailScanner/SpamAssassin have a failed x-header put in, when this message passed through the Exchange server that has SMTP Tracker loaded on it, it adds whatever MS specific data that assigns it an SCL of 9.  (Thereby forcing it into a users JunkMail folder)

This also means we can now truly have users take care of their own white listing.  They can add anyone to their "Safe Sender" list and we don't have to whitelist anything any more at the MailScanner/SpamAssassin/Sendmail boxes.

What is even better is that it also works for OWA use also for all of our users that access mail externally.  Since the Junk Mail rules are server side.  So anyone they add to their "safe sender list" when in the office also is applied when using OWA externally.
