Answer 1

I was getting the same error as the others, and I added authentication, but it still gives me the error.
All "AutomailingUtility" constants are strings
public class SMTPSender {
private Session session;
public SMTPSender() {
Properties props = new Properties();
props.setProperty("mail.smtp.host", AutomailingUtility.HOST);
props.put("mail.smtp.auth", AutomailingUtility.AUTH);
Authenticator auth = new MyAuthenticator(AutomailingUtility.USERNAME, AutomailingUtility.PASSWORD);
session = Session.getInstance(props, auth);
public void sendMessage(String toUser, String message, String subject) {
try {
Message msg = new MimeMessage(session);
msg.setSubject(subject);
msg.setSentDate(new Date());
InternetAddress ia = new InternetAddress(AutomailingUtility.FROM_ADDRESS);
msg.setFrom(ia);
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toUser));
msg.setText(message);
Transport.send(msg);
} catch (AddressException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
any ideas?
