Sending email in Java using Apache Commons email libs

I am using Apache Commons Email library to send emails, but I am not able to send them via GMail SMTP server.
Can anyone provide sample code which works with GMail SMTP server and others?

I am using the following code which does not work:

String[] recipients = {"receiver@gmail.com"};

SimpleEmail email = new SimpleEmail();
email.setHostName("smtp.gmail.com");
email.setAuthentication("sender@gmail.com", "mypasswd");
email.setDebug(true);
email.setSmtpPort(465);

for (int i = 0; i < recipients.length; i++)
{
    email.addTo(recipients[i]);
}

email.setFrom("sender@gmail.com", "Me");
email.setSubject("Test message");
email.setMsg("This is a simple test of commons-email");
email.send();
Solution

  • Sending emails to the GMail SMTP server requires authentication and SSL. The username and password is pretty straight forward. Make sure you have the following properties set to enable authentication and SSL and it should work.

    mail.smtp.auth=true
mail.smtp.starttls.enable=true

    To the sample code add the following to enabled TLS.

    For API-Versions < 1.3 use:
    email.setTSL(true);
    the method is deprecated for versions >= 1.3, and instead you should use: email.setStartTLSEnabled(true);
