This example demostrates the use of QtSslSocket in a client application. The application connects to an SSL service on any given host and port. If the connection succeeds, the user is given a line edit for entering commands, and a text edit which displays the response from the server. Try this example by connection to your IMAP4 or POP3 server. Chances are that these services are running SSL. The SSL service IMAP4 runs on port 993, and POP3 is on port 995. When communicating with an IMAP4 server, the command "X LOGOUT" will close the connection. With POP3, use the command "QUIT". */ /* This class provides a QDialog popup that is shown by SSLClient.
