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.
