title: How does the static Transport.send() method manage its connections?
body: <p>I have a question about the static <code>javax.mail.Transport.send(Message msg)</code> method. The documentation only says "Note that send is a static method that creates and manages its own connection". Does it mean that the method also closes the connection? What's the difference with the non-static <code>sendMessage(Message msg, Address[] addresses)</code> method? </p>
  
  <p>I have had a couple of errors in production due to bad syntax email addresses passed by the glassfish 3 server turns really slow. I want to discard any connection leaks.</p>
