Here is an example from Peter van der Linden's Just Java 6th edition page
659. I hope it will get you started and you can figure out the rest.

 import java.io.*;
    import java.net.*;
    public class email {

      public static void main(String args[]) throws IOException {
  Socket sock = null;
  BufferedReader bis = null;
  PrintStream ps = null;

                try {
  sock = new Socket("localhost", 25);
   bis = new BufferedReader(
                        new InputStreamReader(sock.getInputStream()));
  ps = new PrintStream(sock.getOutputStream());

  ps.println("mail from: trelford");
  //System.out.println( dis.readLine() );
  // Exercise for student:
  // check all responses from the SMTP server
  // They should all start with "2nn" or "3nn"
  // Any different reply code means a failure to send mail.
  System.out.println(bis.readLine());
                } catch (IOException ioe) {
                   System.out.println("Sorry, your system is not running a
mailserver on port 25");
                   System.exit(0);
                }

  String Addressee= "linden";
  ps.println("rcpt to: " + Addressee);
  //System.out.println( dis.readLine() );
  System.out.println(bis.readLine());

  ps.println("data");
  //System.out.println( dis.readLine() );
  System.out.println(bis.readLine());

  ps.println("This is the message\n that Java sent");
  ps.println(".");
  System.out.println(bis.readLine());

  ps.flush();
  sock.close();
 }
}
