SMTP is a typical client-server protocol: a SMTP client connects to a server and proceeds through a message exchange with the goal of transmitting one or more email messages to the server. The test suite simulates a malicious SMTP client, intent on sending invalid SMTP messages and RFC5322(IMF) or RFC2045(MIME) email messages to the tested server implementation.
