THE ANTI-SPAM AGENT FILTERS
The Anti-Spam filters check messages to see if they are likely to be spam.
• Anti-Spam Agent - DFP – Compares mail messages to known spam from different categories.
• Anti-Spam Agent - Heuristics – Uses regular expressions to determine the likelihood that an e-mail
message is actually Spam.
• Anti-Spam Agent - LexiRules – Analyses words, phrases and patterns commonly found in spam to
identify e-mail messages as possible spam.
You can fine-tune the Anti-Spam Agent filters to your company’s filtering requirements. All of the filters can
be edited in their corresponding property screen.
