Now a Day’s informing the Clients about the successful updation of data or sending other automated information form your Java Programs, either from your Servlets or from your Applications has become a requirement, more than a feature. Here we show how to use the Java Mail API to send a Mail. To Test Program all you need to have is a SMTP address (Which your ISP Provides). 

Before Using this Program, you need to have Javasoft’s JavaMail class files which can be downloaded from here http://www.javasoft.com/products/javamail/index.html

You will also need the JavaBeans^TM Activation Framework extension or JAF (javax.activation). It is available at http://java.sun.com/beans/glasgow/jaf.html.

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

public void postMail( String recipients[ ], String subject, String message , String from) throws MessagingException
{
    boolean debug = false;  //Set the host smtp address
    Properties props = new Properties();
    props.put(”mail.smtp.host”, “smtp.jcom.net“);  // create some properties and get the default Session
    Session session = Session.getDefaultInstance(props, null);
    session.setDebug(debug);  // create a message
    Message msg = new MimeMessage(session);  // set the from and to address
    InternetAddress addressFrom = new InternetAddress(from);
    msg.setFrom(addressFrom);

    InternetAddress[] addressTo = new InternetAddress[recipients.length];
    
    for (int i = 0; i < recipients.length; i++)
    {
        addressTo[i] = new InternetAddress(recipients[i]);
    }
   
    msg.setRecipients(Message.RecipientType.TO, addressTo);
  
    // Optional : You can also set your custom headers in the Email if you Want
    msg.addHeader(”MyHeaderName”, “myHeaderValue”);
    msg.setSubject(subject); // Setting the Subject and Content Type
    msg.setContent(message, “text/plain”);
    Transport.send(msg);
}

To Send a Email, from your Program, just call the above method, With the following parameters,
String to — Email Address of the Recipient

String subject — Email Subject

String message — Content or Body of the Message

String from — Your (Senders) Email Address

smtp.jcom.net — Replace this with your ISP’s SMTP address.

That’s it, you are all set to send a Email.

If your SMTP Server need you to do Authentication using Username and Password before Sending out mail, download the complete code from here
SendMailUsingAuthentication.java

InternetAddress kime = new InternetAddress(epst,isim);
InternetAddress kimden = new InternetAddress(”mail@mail.com”,”Admin”);

Properties props = new Properties();
props.setProperty(”mail.transport.protocol”, “smtp”);
props.setProperty(”mail.host”, “10.10.0.11″);
props.setProperty(”mail.user”, “adm”);
props.setProperty(”mail.password”, “123″);

props.setProperty(”useUnicode”, “true”);
props.setProperty(”characterEncoding”, “UTF-8″);
Session oturum = Session.getDefaultInstance(props, null);
Message mesaj = new MimeMessage(oturum);

mesaj.addRecipient(Message.RecipientType.TO, kime);
mesaj.setContent(”Bu mail size E-Bülten‘e kayıt olduğunuz için gönderilmiştir.”, “text/html”);
mesaj.setSubject(”SK E-Bülten”);
mesaj.setFrom(kimden);
Transport.send(mesaj);
