Last Updated September 05, 2016
How should I configure Symantec Mail Security for Microsoft Exchange (SMSMSE) to block Spam and Viral content?
Initial configuration after a new installation or configuration changes based on missed spam or missed virus getting through the filter and entering the environment.
See attached PDF for an overview of potential configurations by category (below)
Out-of the box configuration. No AntiSpam and only basic AntiVirus
Minimum configuration for taking action on spam messages. 1 in 1 Million false positive rate
Practical recommendations that will improve AntiSpam effectiveness without significantly increasing the risk of false positives. This is generally the configuration recommended by Technical Support
Support does not recommend utilizing content filtering for AntiSpam as it is not only time consuming but ineffectual. In some rare cases though, there can be specific solutions that can only be achieved with Content Filtering. Please note that any creation, modifications, or testing of content filtering rules is outside the scope of technical support.
Basic configuration for the AntiVirus engine
Practical recommendations that will improve AntiVirus effectiveness without significantly increasing the risk of taking action on legitimate files. This is generally the configuration recommended by Technical Support
Increases the scope of scanning and implies a more aggressive, and time-consuming approach to antivirus in the environment. Please note that Support does not assist in the creation or testing of content filtering rules.
Potentially over-aggressive filtering that could result in false positives if full knowledge of the items being enabled is not well known and proper due dilligance has not been executed. Please note this configuration is likely unsafe if any modification to content filtering rules has occurred. This configuration is also very likely to impact performance.
