Here is a copy and paste from the site showing Ports and SMTP Server. Credit goes to john wiggins

     jwsmtp::mailer mail(to.c_str( ),
                     from.c_str( ),
                     subject.c_str( ),
                     mailmessage.c_str( ),
                     smtpserver.c_str( ),
                     jwsmtp::mailer::SMTP_PORT,
                     false);

To Authenticate

mail.username("loginname");
mail.password("secret");
mail.authtype(mailer::PLAIN);  

Currently only LOGIN and PLAIN authentication are supported, LOGIN by default, to set to PLAIN call the authtype function

Your ISP could be blocking the secure SMTP port.

You could try to the same in Thunderbird and verify that the port is open first.

Sending to GMail over SSL connection on port 465 does work, and in a straightforward way. You establish connection, you do SSL initialization/handshake, then send EHLO command and it is the usual way from there. You also need login or plain authentication with the server to make it accept your messages.
