I am trying to write a simple
mail sender class that would receive a bunch of arguments and using those will send an email out using our Exchange 2010 server. While authentication etc. seem to work fine, I am getting the following exception when the code is actually trying to send the email (I think). I have ensured that the authentication is working and I get a transport back from the session, but still it fails. Could anyone shed some like on what I am doing wrong or missing? Thanks.
Exception:
javax.
mail.MessagingException: [EOF]

String subject = "Test Email";
String body = "Hi there. This is a test email!";
MailSender.sendHTMLEmail( from, to, host, user, password, subject, body );
}
}
EDIT: I turned on debugging and it says
MAIL FROM:<
[email protected]> 530 5.7.1 Client was not authenticated
DEBUG SMTP: got response code 530, with response: 530 5.7.1 Client was not authenticated.
Why would that be when the session authentication succeded?
