Types of Spam Filters

By: Eddie Tobey

A spam filter is a web-based program which helps to prevent spam e-mail from entering your inbox. Password filter, blacklist and, whitelist filters, challenge/response filter, rules-based filter, community-based filter, and adaptive/Bayesian filter are among the common types of spam filters used nowadays.

Password filters are the basic form of filtering commonly used. These block e-mails without password in the subject line. E-mails containing a pre-set password in the subject line alone are accepted. But, this filter might sometimes block desirable messages also.

Blacklist is another filtering solution which blocks e-mail messages from banned senders. Whitelist filters accept messages only from approved senders. Challenge/response filters such as MailFrontier and Matador will not accept an unapproved sender's e-mail messages until response to challenge arrives. As this filter has some serious drawbacks, it is not considered a perfect solution for spam.

Rules based filter is another popular type of spam filter which blocks mail depending on a pre-determined set of rules. These have a tendency to reject numerous legitimate e-mails. Sophisticated rules based filter solutions such as Spamassassin are more effective. These help to catch 90-95% of spam by finding exclamation points, specific words and phrases, malformed header, and odd punctuations.

A community-based filter, SpamNet is another effective tool, which blocks mail based on community agreement that it is junk. When a user receives a spam message, the message is mailed to the central server, where a fingerprint of the information is stored. The filter blocks the message from user's inboxes, when a number of people have voted the message as spam.

Adaptive / Bayesian filter is among the most popular and new type of filters available now. These utilize a mathematical formula to examine the content of a message. This filter learns user's preferences and accepts only the messages, which are desirable.
