JavaMail Send Email, The JavaMail API is the concept related to email through the JavaMail. There are so many ways to send an email using JavaMail, but here by using SMTP server should send the emails.JavaMail API also provides core classes for to define objects and used that objects to maintain a mail system. To send an email SMTP is the protocol. “Simple Mail Transfer Protocol”, which issues a instrument to deliver the electronic mail(Email). An authentication is required in case of sending and receiving the emails through SMTP server which was provided by host server. An SMTP server also uses the Postcast server, ApacheJames server.

Steps to follow while sending an email:
For sending email by JavaMail involves session, transport object.

Let us see the example how to send the email using javaMail API

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 SendEmail 
{
   public static void main(String[] args) 
   {
      // Mention the recipients email address
      String to = "splessons@gmail.com";

      // Mention the senders email address
      String from = "splessons11@gmail.com";
      final String username = "splessons";//change accordingly
      final String password = "******";//change accordingly
      // Assuming that sending email through relay.jangosmtp.net
      String host = "relay.jangosmtp.net";
      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", "25");

      // To get the Session object.
      Session session = Session.getInstance(props,
         new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
               return new PasswordAuthentication(username, password);
	   }
         });
      try {
	   // Creating a default Mime Message object.
	   Message message = new MimeMessage(session);
	
	   // To set header filed 
	   message.setFrom(new InternetAddress(from));
	
	   // To set header filed 
	   message.setRecipients(Message.RecipientType.TO,
               InternetAddress.parse(to));
	
	   // To set subject to header filed 
	   message.setSubject("Test Subject");
	
	   // To set the actual message
	   message.setText("Hello, this is sample for to check send " +
		"email using JavaMailAPI ");

	   // To send message
	   Transport.send(message);

	   System.out.println("message send");

      } catch (MessagingException e) {
         throw new RuntimeException(e);
      }
   }
}
