Hello JavaMail

พอดีมี project ที่ต้องใช้ JavaMail
ลองเล่นดูหน่อย..
เริ่มแรกไป download JavaMail API มาก่อน
จากนั้นก็ซัดไป

import java.util.Date;
import java.util.Properties;

import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;


public class Hello {

 public static void main(String[] args) {
  try {
   String smtpServer = "smtp.yourdomain.com";
   String to = "youraccount@yourdomain.com";
   String from = "me@mydomain.com";
   String subject = "hello";
   String body = "test message";
   System.out.println("send mail " + smtpServer );
   System.out.println("from: " + from);
   System.out.println("to: " + to);
   send(smtpServer, to, from, subject, body);
   System.out.println("--- complete ---");
  } catch (Exception ex) {
    ex.printStackTrace();  
  }
 }
 
 public static void send(String smtpServer, String to, String from, String subject, String body) {
  try {
   Properties props = System.getProperties();
   props.put("mail.smtp.host", smtpServer);
   Session session = Session.getDefaultInstance(props, null);
   
   Message msg = new MimeMessage(session);
   msg.setFrom(new InternetAddress(from));
   msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to, false));
   msg.setSubject(subject);
   msg.setText(body);
   msg.setHeader("X-Mailer", "LOTONtechEmail");
   msg.setSentDate(new Date());
   
   Transport transport = session.getTransport("smtps");
   transport.send(msg);
   System.out.println("Message send OK.");
  } catch (Exception ex) {
   ex.printStackTrace();
  }
 }
 
}
