Also, you have to check the return codes for SSL_read and SSL_write, since they may say that you need to write or read again (remember, there is an entire layer happening between the cleartext and the TCP session, and SSL_read and SSL_write, which may or may not want to follow your simple in/out regime above). Also, what does the server say when you use s_client and do all of that on the command line? You're not actually checking in the above if the USER returned OK, and you might want to do that, because the problem could be as simple as the other end hanging up when you don't give a correct USER.)
