SMTP Client Test Suite
Direction:
Client

SMTP is a typical client-server protocol: an 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 server, intent on sending invalid SMTP reply messages to the tested client implementation.
