A system and method of filtering junk e-mails. The user is provided with or compiles a list of e-mail addresses or character strings which the user would not wish to receive to produce a first filter. A second filter is provided including names and character strings which the user wishes to receive. Any e-mail addresses or strings contained in the first filter will be automatically eliminated from the users system. Any e-mail addresses or strings contained in the second filter would be automatically sent to the users "In Box". Any e-mail not provided in either of the filter lists will be sent to a "Waiting Room" for user review. If this user review results in the user rejecting any e-mail, the address as well as specific character strings included in this e-mail would be transmitted to a central location to be included in a master list. This master list is periodically sent to each of the users allowing the first filter to be updated.
