Some users want to aggressively stop all Backscatter. Using SpamSentinel version 7.5.3.6, you can block even more Backscatter right at your Domino server. Here are the settings from the SpamSentinelAdmin.nsf server config document:



Notice the Aggressive option. This will block the most common Backscatter offenders, such as Challenge / Response systems, EML attachments, Delivery Failures and Out of Office Replies. It will also block some real delivery failure reports or out of office replies, and should only be used if you are getting hundreds or thousands of these Backscatter emails every day. These aggressive options are best turned on for a week until the Backscatter subsides. They can be changed in real-time, without restarting the Domino server.

If your Lotus Notes email users get one or two a day, we recommend the "Normal Settings" and that you deselect the "Aggressive Backscatter Prevention" settings.
