Without the pain of building complex filters, KTS is able to filter unsolicited e-mails. KTS does not need to maintain a list of spammers. Maintaining such a list is not efficient. True spammers change the method they use every time, so they reach your e-mail boxes even when listed. KTS uses a unique algorithm to determine whether or not a message is spam. KTS is customizable, giving you full control over how each message is treated.
