530 5.7.1 Client was not authenticated

Hi,

While sending Email... I keep getting error:

530 5.7.1 Client was not authenticated

Initially I thought that the "fromaddress" that I am using requires an authentication. But that is not the case. It has been configured to send mail without any authentication. Then when I changed the configuration to enabled authentication, I am still getting the same error. I am putting the whole SMTP Debug as well as my code here. Note that my user id for authentication is same as "from address" i.e. xxxxx@abcd.com

My Java code goes like this:

l_auth = new EmailAuthenticator (l_user, l_passwd);
//EmailAuthenticator extends Authenticator
l_smtp_properties	= new Properties ();
l_smtp_properties.setProperty ("mail.smtp.host", "192.168.21.223");
l_smtp_properties.setProperty ("mail.smtp.from", "xxxxx@abcd.com");
l_smtp_properties.setProperty ("mail.smtp.auth", "true");
smtpSession = Session.getInstance (l_smtp_properties, l_auth);
smtpSession.setDebug (true);
smtpTransport	= smtpSession.getTransport ("smtp");
smtpTransport.connect (smtpSession.getProperty ("mail.smtp.host"), 25, l_user, l_passwd);
l_smtp_message = new MimeMessage (smtpSession);
l_addr[0] 	= new InternetAddress (p_from_addr);
l_smtp_message.addFrom (l_addr);
l_smtp_message.addRecipient (Message.RecipientType.TO, new InternetAddress ("me@gmail.com"));
l_mimemultipart = new MimeMultipart ();
l_inline_part 	= new MimeBodyPart ();
l_inline_part.setDisposition (Part.INLINE);
l_inline_part.setText (p_message,l_encoding);
l_mimemultipart.addBodyPart (l_inline_part);
l_inline_part.setHeader ("Content-Type","text/html;charset="UTF-8"");
l_smtp_message.setSentDate(new java.util.Date());
l_smtp_message.setSubject (MimeUtility.encodeText(p_subject,l_encoding,"B"));
l_smtp_message.setContent (l_mimemultipart);
l_smtp_message.saveChanges();
smtpTransport.sendMessage (l_smtp_message,l_smtp_message.getAllRecipients());

Any idea what I am doing wrong. Once again with authentication and no authentication, I keep getting this same error.

What do you mean, with authentication? There is no authentication in that code. Have a look at the JavaMail FAQ, where you'll find an example of how to do it.

Referring to Java doc link that you posted:

You need to authenticate to your SMTP server. The package javadocs for the com.sun.mail.smtp package describe several methods to do this. The easiest is often to replace the call Transport.send(msg); with

String protocol = "smtp";
props.put("mail." + protocol + ".auth", "true");
...
Transport t = session.getTransport(protocol);
try {
t.connect(username, password);
t.sendMessage(msg, msg.getAllRecipients());
} finally {
t.close();
}

Ain't I doing the same thing:

smtpTransport.connect (smtpSession.getProperty ("mail.smtp.host"), 25, l_user, l_passwd);
....
smtpTransport.sendMessage (l_smtp_message,l_smtp_message.getAllRecipients());

only difference being which overloaded connect method I am using? Or am I missing something?

Yes. The code you showed from the FAQ provides a user ID and password. Your code (which the server doesn't believe authenticates) does not provide a user ID and password. Do you think that is an insignificant difference?

If You are referring to variable l_user, l_passwd then this is getting populated from my Properties file for which I haven't pasted the code here.
l_user = xxxxx@abdc.com
l_passwd = xxxxxxxx

No, of course just setting variables in your code to the user ID and password wouldn't cause authentication with the SMTP server. So no, I wasn't referring to that. I was referring to the total absence of any code where you pass that information to the server. Or if you do, I can't see it. (My apologies if it's actually there -- I find your code very hard to read with all those strange variable names.)

But you've seen the example code. It works. Your code is different, and it doesn't work. I know what I would do in that case. I'm surprised you haven't done it yourself already.
