When I send mail Then Found Error javax.mail.AuthenticationFailedException: 535 Invalid authentication data
I got the following error when sending email with the code below
javax.mail.AuthenticationFailedException: 535 Incorrect authentication data
What could be the problem in my code.
public class SendMail {
public static boolean sendHTMLMail(final String from, final String password, String senderName, String sub, String msg, String[] to) {
String host = "mail.xxxx.org";
MimeMultipart multipart = new MimeMultipart();
MimeBodyPart bodypart = new MimeBodyPart();
Properties p = new Properties();
p.setProperty("mail.smtp.host", host);
p.put("mail.smtp.port", 587);
p.put("mail.smtp.auth", "true");
try {
Session session = Session.getInstance(p, new javax.mail.Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(from, password);
}
});
Transport transport = session.getTransport("smtp");
MimeMessage mimeMessage = new MimeMessage(session);
mimeMessage.setFrom(new InternetAddress("" + senderName + "<" + from + ">"));
InternetAddress[] toAddress = new InternetAddress[to.length];
for (int i = 0; i < to.length; i++) {
toAddress[i] = new InternetAddress(to[i]);
}
for (InternetAddress toAddres : toAddress) {
mimeMessage.addRecipient(Message.RecipientType.TO, toAddres);
}
bodypart.setContent(msg, "text/html; charset=\"utf-8\"");
multipart.addBodyPart(bodypart);
mimeMessage.setSubject(sub);
mimeMessage.setContent(multipart);
transport.connect(host, from, password);
mimeMessage.saveChanges();
Transport.send(mimeMessage);
transport.close();
return true;
} catch (MessagingException me) {
me.printStackTrace();
}
return false;
}
}
