Writing a program that sending e-mails , Please help

Question

Hello ,
I want to write a program that gets
the the user email (the server of the email , it's username and passowrd)
and the reciver email , and the message , and sending the message from the
user's email to the reciver email.
But I want to write by myself a class that connects to the user's email
and not to use Smtp classes....
(I know how to use Sockets , etc...)
But I actually dont know where to start from...
Okay ,I know that first of all I need to get from ther user the server of his email , his username
and his password.
(I will take Gmail for example)
So I create a Socket
Socket mySocker = null;
try
mySocket = new Socket("smtp.gmail.com" , 465);
} catch (UnknownHostException e) {
            System.err.println("Don't know about host : Gmail.");
            System.exit(1);
} catch (IOException e) {
            System.err.println("Couldn't get I/O for the connection to: Gmail.");
            System.exit(1);
        }but from here , how do I connect the user's email with the password and the username that he gave me..?

(I know how to use Sockets , etc...)If you're going to connect to SMTP servers, you'll make a socket connection to the default port and then....send....SMTP commands....so.....it'll.....understand.....you.
Geez, if you want to learn how to write SMTP from scratch this makes sense, but if you just want to send e-mail I'd reconsider and just download JavaMail.
%I am not doing it becuase I need it , I am doing to train :)
and do you have any list of SMTP commads or somthing like that??
