Running Forefront Protection for Exchange 2010 on our mailbox and hub transport server. Forefront Content Filtering SCL Thresholds and Actions are Allow SCL -1 through 4, Quarantine SCL 5-9.
We are interested in experimenting with the SCL behaviors but unfortunately the Forefront for Exchange 2010 GUI interface doesnt offer a lot of granularity in this regard. For example, you can relax the behavior to Stamp header and continue processing for SCL 5-6 but then SCL 7-9 must be either Reject or Delete (no option for Quarantine). We were hoping to experiment with Stamp header and continue processing for SCL 5-6 and Quarantine 7-9 (or perhaps Reject 9). Perhaps I am missing an obvious setting or workaround? Since our current Exchange organization SCLJunkThreshold setting is 8 and we are Quarantining SCL 5-9, our users no longer see any email routed to their Outlook Junk E-mail folder (with the exception of the client side filtering Outlook can perform which is different than the Exchange side routing). Can I set SCLJunkThreshold for that specific server?
I tried some of the Exchange Set-Mailbox options: "Set-Mailbox -Identity foo -SCLQuarantineThreshold 7" but that didn't seem to affect the Forefront behaviors (didn't restart the Microsoft Exchange Information Store).
Can someone give me a push in the right direction?
