4.3.1.4 Antispam protection
Unsolicited email, called spam, ranks among the greatest problems of electronic communication. Spam represents
up to 80 percent of all email communication. Antispam protection serves to protect against this problem. Combining
several email security principles, the Antispam module provides superior filtering to keep your inbox clean.
One important principle for spam detection is the ability to recognize unsolicited email based on predefined
trusted addresses (whitelist) and spam addresses (blacklist). All addresses from your contact list are automatically
added to the whitelist, as well as all other addresses you mark as safe.
The primary method used to detect spam is the scanning of email message properties. Received messages are
scanned for basic Antispam criteria (message definitions, statistical heuristics, recognizing algorithms and other
unique methods) and the resulting index value determines whether a message is spam or not.
Antispam protection in ESET Smart Security allows you to set different parameters to work with mailing lists.
Options are as follows:
Message processing
Add text to email subject – Enables you to add a custom prefix string to the subject line of messages that have been
classified as spam. The default is "[SPAM]".
Move messages to spam folder – When enabled, spam messages will be moved to the default junk email folder.
Use the folder – This option moves spam to a user-defined folder.
Mark spam messages as read – Select this to automatically mark spam as read. It will help you to focus your
attention on "clean" messages.
Mark reclassified messages as unread – Messages originally classified as spam, but later marked as “clean" will be
displayed as unread.
