Java MAil API composed of classes and some Interfaces which is used to send(compose) , read(fetch) and delete e-mail messages

Sending Simple Text Mail:

To send a simple Text Mail you can follow the following steps:

1. Get a Session object which handles configuration setting and authentication and stores all the information of host like host name, username, password etc.

2. Create a default MimeMessage object and set the "From","To" attributes & subject of this message.

3. Write and set your actual message as: message.setText("Message Text");

4. Send the message using the Transport object.

Example using Gmail SMTP Server:-

package mail;

import java.util.Properties;

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

public class MailTestGmail {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
          // Specifying Recipient's email ID 
          String To = "xxx@xxx.com";//change accordingly

          // Specifying Sender's email ID
          String From = "xxx@xxx.com";//change accordingly
          final String username = "xxx@xxx.com";//change accordingly
          final String password = "*****";//change accordingly

          // Set up the SMTP server
          String host = "smtp.gmail.com";

          Properties props = new Properties();
          props.put("mail.smtp.auth", "true");
          props.put("mail.smtp.starttls.enable", "true");
          props.put("mail.smtp.host", host);
          props.put("mail.smtp.port", "587");

       // Get the Session object to handle both configuration setting and authentication

        Session session = Session.getInstance(props,
          new javax.mail.Authenticator() {
             protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password);
             }
          });

          try {
             // Create a default MimeMessage object.
             Message msz = new MimeMessage(session);

             // Set the "From" attribute in this Message
             msz.setFrom(new InternetAddress(From));

             // Set the "To" attribute in this Message
             msz.setRecipients(Message.RecipientType.TO,
             InternetAddress.parse(To)); //   You can add multiple recipients by adding their mail address here

             // Set the subject of this message
             msz.setSubject("Testing Subject");

             // Now Write and set the actual message
             msz.setText("Hello, this is sample text for to check send "
                + "using JavaMailAPI ");

                  // Send  the message by send method
             Transport.send(msz);

             System.out.println("Message Sent successfully....");
          } catch (MessagingException e) {
                throw new RuntimeException(e);
          }
    }

}
