Keywords are not strictly words. They can be any of the following:
  • Numbers
  • Typographical characters
  • Short phrases
  • Words or phrases connected by logical operators
  • Words or phrases that use regular expressions

Using Keywords Effectively

ScanMail offers simple and powerful features to create highly specific filters. Consider the following, when creating your Content Filtering rules:
  • By default, ScanMail searches for exact matches of keywords. Use regular expressions to set ScanMail to search for partial matches of keywords.
  • ScanMail analyzes multiple keywords on one line differently than multiple keywords when each word occupies a single line.
  • You can also set ScanMail to search for synonyms of the actual keywords.
  • Try to use exact matching, regular expressions, operators with keywords, and import keywords to the keyword list from previous configurations.
