I am trying to configure an Exchange Server to work with an antispam appliance so that all emails detected as spam by the appliance are sent to the exchange users personal junk folder (if possible without adding any third-party modules to Exchange).
I have read that IMF reads the X-SCL header and sends emails with high SCL values to the junk folder, so I was thinking I could simply add an X-SCL header with the antispam appliance but this does not seem to work. I'm wondering if Exchange doesn't re-classify the message when it is received or something similar.
So I was wondering if it is possible to route emails to the junk folder using an event sink? I have seen ways to send them to the "Badmail" folder but this is not really what is wanted in this case.
