If you turn on session debugging, you'll get a clue as to what you're
doing wrong, but I'll save you the trouble. Your error is here:
props.put("mail.smtp.auth",true);That should be:
props.put("mail.smtp.auth", "true");
BTW, you don't need all that socket factory stuff. See the JavaMail FAQ for a
simpler approach.
