Thread: How to Send emails from Google Mail using JavaMail API

With this code you can send emails through your Google Mail account using the JavaMail API.

Firstly, if you don't already have the JavaMail API, visit JavaMail API and download it.

If any of you need help importing the API, please post.

Here is the code. Update the code with your Google Mail account details.

import javax.mail.*;
import javax.mail.internet.*;
import java.util.Properties;
 
public class SimpleGoogleEmail {
 
    private static final String SMTP_HOST_NAME = "smtp.gmail.com";
    private static final int SMTP_HOST_PORT = 465;
    private static final String SMTP_AUTH_USER = "username@gmail.com";
    private static final String SMTP_AUTH_PWD  = "yourPassword";
 
    public static void main(String[] args) throws Exception{
       new SimpleGoogleEmail().test();
    }
 
    public void test() throws Exception{
        Properties props = new Properties();
 
        props.put("mail.transport.protocol", "smtps");
        props.put("mail.smtps.host", SMTP_HOST_NAME);
        props.put("mail.smtps.auth", "true");
        // props.put("mail.smtps.quitwait", "false");
 
        Session mailSession = Session.getDefaultInstance(props);
        mailSession.setDebug(true);
        Transport transport = mailSession.getTransport();
 
        MimeMessage message = new MimeMessage(mailSession);
        // message subject
        message.setSubject("Java Programming Forums");
        // message body
        message.setContent("Hey! Visit http://www.JavaProgrammingForums.com", "text/plain");
 
        message.addRecipient(Message.RecipientType.TO,
             new InternetAddress("from@emailaddress.com"));
 
        transport.connect
          (SMTP_HOST_NAME, SMTP_HOST_PORT, SMTP_AUTH_USER, SMTP_AUTH_PWD);
 
        transport.sendMessage(message,
            message.getRecipients(Message.RecipientType.TO));
        transport.close();
    }
}

		message.setContent(mp);

To set the body/message

The old way still works. There is no need to use MultiPart if the email is plain text and does not contain attachments or inlines.
