Why do I need an EMail Filter?
Many people receive annoying EMail which they do not wish to receive. Frequently, the unwanted mail is advertising which you did not request. Many people find this unwanted EMail to be frustrating and it is often difficult to induce the sender to stop sending it to you. Some people never receive unwanted EMail; those people do not need a filter. Others have had the misfortune of having their name placed on a mailing list which has been sold to many different spammers and receive a lot of junk mail.
