Bulk Complaint Level (BLC) Transport Rule and High Confidence Quarantine

Thanks for the reply Vasil.  I am positive that it isn't the Outlook clients.  This processing of the email is done prior to it ever being recieced by the mailbox.  Also, due to the vast nature of the emails I am needing excluded, I've tried to stay away from creating rules using words or phrases.  This technet article below is one of several that I have been working off of.  It has a section for the X-Microsoft-Antispam header I had mentioned as well as the comments about the SCL being set by the BCL scoring.  I'm needing the BCL to be ignored, so removing that headed seemed the most logical.
