How do I change the setFrom() method to whatever I want? I can send e-mails through my gmail accoutn and change the setFrom text, but it shows my username for the email. I have tried using my yahoo account as well and I get an authentication error.

I want to change the from address. The code is as follows:

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 SendMailTLS {

public static void main(String[] args) {

final String username = “username@gmail.com”;

final String password = “password”;

Properties props = new Properties();

props.put(“mail.smtp.auth”, “true”);

props.put(“mail.smtp.starttls.enable”, “true”);

props.put(“mail.smtp.host”, “smtp.gmail.com”);

props.put(“mail.smtp.port”, “587”);

Session session = Session.getInstance(props,

new javax.mail.Authenticator() {

protected PasswordAuthentication getPasswordAuthentication() {

return new PasswordAuthentication(username, password);

}

}

);

try {

Message message = new MimeMessage(session);

message.setFrom(new InternetAddress(“from-email@gmail.com”));

message.setRecipients(Message.RecipientType.TO,

InternetAddress.parse(“to-email@gmail.com”));

message.setSubject(“Testing Subject”);

message.setText(“Dear Mail Crawler,”

+ “\n\n No spam to my email, please!”);

Transport.send(message);

System.out.println(“Done”);

} catch (MessagingException e) {

throw new RuntimeException(e);

}

}

}

Faced Same problem while using “smtp.gmail.com”.

Use Mandrill,it will work.

Once you setup a Mandrill account,use “smtp.mandrillapp.com” on port 587.

For Authentication,set username=your mandrill username and password=API key generated in your account.
