PROBLEM:
I'm trying to use JavaMail to send email from an EC2 Ubuntu 12.04 Server but it's not working.
BACKGROUND:
I intend to send an auto generated mail from a Tomcat Server to a few team members. I used JavaMail 1.4.7 for this task and I've successfully tried it on a local installation of Tomcat (on a personal laptop).
The next step was where I put this module on an EC2 Server but it started failing with the below given error:
ERROR:
DEBUG SMTP: AUTH LOGIN failed javax.mail.AuthenticationFailedException: 535-5.7.1 Username and Password not accepted. Learn more at 535 5.7.1 http://support.google.com/mail/bin/answer.py?answer=14257 j13sm1603739pat.17 - gsmtp

at javax.mail.Service.connect(Service.java:176)
Code Snippet:
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
Properties props = new Properties();
props.put("mail.smtps.host","smtp.gmail.com");
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtps.auth", "true");
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.port", 465);
props.put("mail.smtp.socketFactory.port", 465);
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
props.put("mail.smtp.ssl.enable", true);
Session session = Session.getDefaultInstance(props);
session.setDebug(debug);
Message msg = new MimeMessage(session);
InternetAddress addressFrom = new InternetAddress("[email protected]");
msg.setFrom(addressFrom);
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++) {
addressTo[i] = new InternetAddress(recipients[i]);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);
msg.setSubject("test subject");
msg.setContent("test message", "text/plain");
Transport tp = session.getTransport("smtp");
tp.connect(SMTP_HOST_NAME, "[email protected]", "dummypassword");
tp.sendMessage(msg, addressTo);
tp.close();
ADDITIONAL INFO:
- I've added permissions for all ports on the EC2 instance. Also, I've added explicit permissions for ports 465(SMTPS) and 25(SMTP).
- I've cross checked the correctness of the username and password provided in the code.
