Resumen:
The Simple Mail Transfer Protocol (SMTP) is the TCP/IP standard for the
electronic mail transfer from one computer to another. It does not address
security aspects, like catching the message or faking the sender. Today, to
avoid non-authorized e-mail access or modification, one needs to use tools
external to the e-mail software or to depend on a complex infrastructure for
cryptography key distribution. This work specifies the Secure Simple Mail
Transfer Protocol (SSMTP), which is an SMTP secure extension. It was
designed to be easily integrated within the e-mail software and to run
independently of any distribution key supporting service. Besides SSMTP, this
work also defines the Local Mail Security Procedures (LMSP) to assure e-mail
servers local security.
