Send mail in javax.mail without authentication

Question

I am using javax.mail to send mails in Java. Now that a part of the concept of my project changed I have to send a mail without authentication. I will have to change my createSession() method:

private void createSession() {     properties.put("mail.smtp.auth", "true");     properties.put("mail.smtp.starttls.enable", "true");     properties.put("mail.smtp.host", server);     properties.put("mail.smtp.port", port);      session = Session.getInstance(properties, new javax.mail.Authenticator() {         protected PasswordAuthentication getPasswordAuthentication() {             return new PasswordAuthentication(username, password);         }     }); } 

It is rather obvious that I should change mail.smtp.auth to false, but what else should I change?

Answer 1

private void createSession() {     properties.put("mail.smtp.auth", "false");      //Put below to false, if no https is needed     properties.put("mail.smtp.starttls.enable", "true");     properties.put("mail.smtp.host", server);     properties.put("mail.smtp.port", port);      session = Session.getInstance(properties); } 

I think, this would suffice.
