If you frequently receive junk E-mail from a particular site or address, you can filter that mail to one location and throw it away with just one operation. Novell's GroupWise implements filters as part of its Rules facility. Consult the GroupWise Help file for more information about setting up a mail filtering rule. A previous version of this column talked about mail filtering in Pegasus Mail and for UNIX-based mail systems. E-mail filters are one feature that should not be overlooked if you receive and send multiple messages a day.
Filters can make the process of reading E-mail much easier and more efficient.
