How do I find out why a message is being flagged as SPAM in Outlook 2007 / Exchange 2007?

Posted on 2009-04-20

We have noticed that our server that sends out account information to users often ends up in their Junk E-Mail folder.  

When I send a test message to our Exchange Server (Outlook 2007 / Exchange 2007), I notice the "SCL=7" in the email header, but how do I get a breakdown of why it's a '7'?  Is there a way to access a log that will breakdown the different reasons that makes up the '7'?

    That information isn't made public. Like most antispam vendors Microsoft do not make what they filter on public.

    If you have an internal server that sends messages to internal users then setup a second SMTP virtual server that doesn't have IMF enabled on it. Then the email will not be filtered.

    Thanks Mestha for your post.  Although that sounds like a great idea for internal-internal messages, these messages are for external users for our system and we are going crazy trying to figure out why the messages are getting such a high rating when our IP addresses are not on any blacklist.

    Are there any other services out there that anyone is aware of that can read a message and get a little more information about the SCL?

    What is different from you wanting to know, and a spammer wanting to know?
    Nothing at all. That is why you will find nothing about why the message is being flagged as spam.

    All you can do is make a guess. So if the message is being sent directly from the system rather than through another host, that could be the cause of the problem, particularly if you cannot set the SMTP banner. If it is a HTML formatted message, that can cause the message to appear as spam. Links to other places, embedded images.

    There is no easy answer to this question.
