SMTPs

SMTPs: The TLS secured version of the Simple Mail Transfer Protocol (SMTP), a protocol for sending e-mail messages between servers, and from clients to servers for further transmission (relaying). If a mail server does not implemet some kind of authentication relaying (Open Relay), the server can be abused to retransmit messages to other servers easily obscuring the location of the original sender, a techinique often used by spammers to 'hide' the origin of the messages. BCISGNet implements the relay part by authentication (requiring a login and password) the channel is TLS secured to ensure the authentication details aswell as the content are not transmitted in plain text between the client and the server.
