In response to a match between the portion of the message and the filtering information, the system can employ one of a number of different specified blocking options. The system has an update server that is accessible over the Internet and that has new filtering information for updating the filter database. The filter database can have a filter database stored on a server in a network coupled to the client.Field of SearchDistributed or remote access | |
