One of the most common uses for filters is to keep unsolicited commercial e-mail (or "spam") from apprearing in your mailbox. Filters can be used to redirect the mail to other folders or to the trash.
Below are e-mail programs which have filtering capabilities and StarNet has developed a set of filters to help cut down on the amount of spam appearing in you Inbox.
Note: Outlook Express has filtering ability. However, it isn't flexible enough to be useful in creating general set of filters like the other programs.
