CSM functions as a personal and secured ?badge? that you offer to anyone you choose to communicate via e-mail.
This will let you control whoever has the possibility to write email to you or not, keeping ?spam? and unsolicited e-mail out of your e-mailbox.

This high security level is offered by a system that we will call ?Stamping?.
Stamping will change automatically the ?badge? you have issued every time you use it.
If some unauthorized individual intercept your original badge will not be able to send you undesired e-mail messages, exclusively the senders that you have authorized with stamped CSM will be allowed to do so.
The two elements you need to operate this software are:
CSM Controller
CSM Client
