SFM eliminates spam by reversing the paradigm of electronic mail, while retaining its traditional simplicity and convenience. With the old paradigm, your E-mail address provides a global point of contact, whereby anybody knowing it is allowed to send you a message. The system is inherently open, which means that there is no effective way to keep spam out of your mailbox. With SFM, your contacts receive different (personalized) E-mail addresses of yourself confined to those contacts. This eliminates address harvesting by rendering it futile.
