Why am I getting a nulljavax.mail.AuthenticationFailedException? - email

Question

I am making a web app that sends emails automatically, so I am using javamail. I need to use the SMPT of my company, and no matter what I do I get a nulljavax.mail.AuthenticationFailedException. This is the first time I have used it and I'm really frustrated since I have tried a wide number of solutions and still I can't figure out what's wrong. I made a test using gmail and it worked, but so far nothing has helped. here's my code:
UPDATE: I have made changes to my code, and got rid of the authenticator as suggested.
final String username = "dva.clamadrid#grupoautofin.com";
final String password = "Leprechaun01";
Properties props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.auth", "true");
Session session = Session.getInstance(props);
try {
session.setDebug(true);
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("dva.clamadrid#grupoautofin.com"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("dva.clamadrid#grupoautofin.com"));
message.setRecipients(Message.RecipientType.CC,
InternetAddress.parse(Copy));
message.setSubject("Testing Subject");
message.setText("Dear Mail Crawler,"
+ "\n\n No spam to my email, please!");
Transport transport = session.getTransport("smtp");
transport.connect("SMTP.grupoautofin.com", 25, username, password);
transport.sendMessage(message, message.getAllRecipients());
transport.close();
Log.i("Estás enviando: ",""+message.toString());
System.out.println("Done");
}catch(AuthenticationFailedException e) {
Log.e("ERROR DE AUTENTIFICACION: ",""+e.getMessage()+e);
e.printStackTrace();
bandera = false;
} catch (MessagingException e) {
bandera=false;
Log.e("ERROR ENVIANDO: ",""+e.getMessage()+e);
e.printStackTrace();
//throw new RuntimeException(e);
}
Also, my Error Log, now with Debug Messages:

Still getting the same error, what else am I doing wrong? Thanks in advance.

Answer 1

First, you don't need the Authenticator, get rid of it.
Second, you don't need the host, port, or auth properties if you're going to call the connect method explicitly so you can get rid of them too.
You've done something to verify that you're passing the correct username and password, right?
Turn on session debugging and the debug output might provide more clues as to what's going wrong. You might need to set the "mail.debug.auth" property to "true" to see the full authentication protocol exchange (which will include your password) to see the details of what's failing. If you still can't figure it out, post the debug output (without the authentication exchange).
