Blocking unwanted email messages 6 See "Manage how Norton AntiSpam detects spam" on page 28. w Norton AntiSpam uses a pattern-matching engine that automatically compares the contents of incoming email messages to a list of spam characteristics. If the message contains many spam characteristics, it is more likely to be spam than a message that contains few spam characteristics. Based on this analysis, Norton AntiSpam estimates the likelihood that the message is spam. Norton AntiSpam uses the settings you've chosen to determine which messages are marked as spam. If Norton AntiSpam is set to Low, messages must contain many spam characteristics before they are flagged as spam. If Norton AntiSpam is set to High, messages that contain only a few spam characteristics are flagged. Some email servers use SSL (Secure Sockets Layer) connections to encrypt connections between your computer and the server. Norton AntiSpam cannot scan email messages received via SSL connections. Create spam filters When a message is identified as spam, Norton AntiSpam appends Norton AntiSpam: to the beginning of the message's subject. You can then use your email program to create filtering rules for all email messages containing this text if you so desire. w If you use Microsoft Outlook Express, Microsoft Outlook, or Eudora, you do not need to create spam filters.
