We just get setup with McAfeee Saas Email Protection thru our Internet Vendor. Things are looking good so far, however, I am looking for Best Practices involving our SBS Exchange 2007 server. Currently Anti-Spam is Enabled, and I am seeing "good" messages that I think are being blocked by our Exchange server. In the Message Audit screen, I am seeing the following:
Message Disposition: [550 Backend Replied [4c3a0335.0.1480594.00-1870.2211237.p02c11m096.mxlogic.net]: 5.7.1 Message rejected as spam by Content Filtering. (Mode: normal); Backend TLS: yes;
Is it best practices with having SaaS Email Protection to disable the Anti-spam on Exchange and just let McAfee do all the scanning?
Yes, that error message indicates that the Exchange level anti-spam is blocking the message. Redunant spam filtering can cause issues as it creates multiple points of potential failure. We generally do recommend disabling local Anti-Spam on the server since this processing has been off-loaded to the SaaS Cloud.
