In case of POP3 it is possible to connect via telnet using sockets over
port 110, But how to do it , if SPOP3 is implemented. With normal telnet
it can be done quite easily with
   Socket pop3Socket = new Socket(, 110);

FYI: For connecting to SPOP3 we use in linux/unix
   openssl s_client -connect


You'll need to use the SSLSocket class. An example can be found at:

Basically, you'll do something like:
   SSLSocketFactory f = (SSLSocketFactory) SSLSocketFactory.getDefault();
   SSLSocket c =        (SSLSocket) f.createSocket("localhost", 8888);
