Java EE (Java Enterprise Edition) General Discussion

Hello,
I have a problem I have been trying to solve for about a month now. I have an email server James (latest version) setup on Linux and configured to accept authenticated SMTP connections. I know it works fine because I have been using it with Outlook Express for sometime now. I am now trying to send email from Java through James. I used to do it through Yahoo, but Yahoo is not free anymore, so I am trying to use my own server. If I disable authentication on James, I can send emails with no problems. If I enable SMTP authentication, then I can only send email to local users. The exception I am getting is:

javax.mail.SendFailedException: Sending failed;
nested exception is:
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
javax.mail.SendFailedException: 530 Authentication Required

at javax.mail.Transport.send0(Transport.java:219)
at javax.mail.Transport.send(Transport.java:81)
at com.andrey.email.test.main(test.java:51)
Exception in thread "main"


The address I am using is valid. I think the real exception is 530 Authentication Required. I have tried everything I found on this forum and still can't get it to work. The code is below. If anyone has any ideas, I would really appreciate it.

thanks
