Antispam When enabled, the antispam filter checks email messages
for spam and phishing characteristics. The filter
identifies messages as spam based on the
selected catch rate.
The antispam filter uses a Web Reputation and spam
prevention filter to stop spam from entering your network.
The antispam filter can use two approaches when
detecting spam:
• Spam: This setting is very conservative. Almost
every "spam" detection is truly an unwanted email
message. This setting has the following actions:
Delete and Quarantine.
• Potential Spam: This setting is more aggressive.
However, there may be some messages marked
as "spam" that may be legitimate email
messages. This setting has the following actions:
Delete, Quarantine, and Pass.
