Domain Email going into Junk-Email Folder

dparkes used Ask the Experts™
We have Exchange Server 2007 along with Outlook 2007 clients, and many emails within our own domain are going into the Junk Email folder in Outlook.  This seems to happen system wide, not just on one PC.  The emails being blocked are most often automated internal notifications.  

It doesn't help to use the option "Mark as not Junk".  A message comes up saying the mail will be moved to the Inbox, but it isn't.

When we use the option "Add sender to safe sender's list" we get the message: "The e-mail address for this sender is internal to you organization and cannot be added to this list."

And to make things even more fun, sometimes messages from a particular account get blocked and sometimes they don't.

The only thing I can think of doing is turning the Junk Email feature off, since it only very rarely finds a real junk email anyway.  Is there any way, though, to get this to work?

In Junk Email settings, the Level of Protection is set to Low. On the Safe Senders list, is listed.  

The emails being blocked were being received for many months, and just a few days ago they started being filterd into Junk Email.

Edit: For even more fun... Even after I turn off Automatic Filtering, our own Email notifications still get blocked.  Thanks, MS!

Emails sent with you domain name, but not from your Exchange server will get tagged as junk. Does that apply in this case?

Run the following PS:

set-contentfilterconfig -bypassedsenderdomains

I tried that, but it didn't work.  I think the issue may be authentication related.
