One of the scourges of the Internet is the high volume of unsolicited email (popularly known as ‘spam’). It can be a tiresome time-waster and can often be the bearer of computer viruses.

For busy email addresses (especially emails that are advertised on a web page) a spam filter is a useful time-saver. It recognises well-known ‘spammers’ and deletes their messages. It can also be individually configured to bar messages from spammers you discover from your own experience.
