SMTP autnehtication does not appear to happen

Question

I am attempting to use SMTP authentication with a mirapoint
SMTP server that supports authentication. In the debug
output, useAuth is set to true. The server does not
announce that it supports the AUTH extension. Is this enough
to prevent JavaMail from sending the AUTH command
even though I requested smtp authentication from java mail?
I tried provided the authentication information in the
Transport connect call and in an authenticatior but the
information never gets sent to the server. The server I am
"supports" authentication, but does not require it.
Code:
Properties props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "smtp");
session = Session.getDefaultInstance(props, new SMTPAuthenticator());
session.setDebug(true);
msg.saveChanges();
Transport t = getSession().getTransport(); // session from above
t.connect(host, user, password);
t.sendMessage(msg, msg.getAllRecipients());
Server announced extensions:
250-8BITMIME
250-SIZE 62914560
250-DSN
250-ETRN
250-STARTTLS

Hi, Fred:
I think you need to put the user name & pwd into the SMTPAuthenticator. The SMTPAuthenticator should have a method for you to put the pair in. If there is not, you can implement your own Authenticator by yourself. Just extend the class Authenticator, and implement the function
public PasswordAuthentication getPasswordAuthentication()
Good Luck!
