Java EE (Java Enterprise Edition) General Discussion

Hello Friends,

I created a simple test application to connect to and read mail from Win 2003 POP3 Service (No Exchange Server). Without using SPA (Secure Password Authentication), the code runs fine.

But if I turn on SPA, following error is encountered

-----
DEBUG: setDebug: JavaMail version 1.4.1
DEBUG: getProvider() returning javax.mail.Provider[STORE,pop3,com.sun.mail.pop3.
POP3Store,Sun Microsystems, Inc]

Now if I enable apop for POP3 by adding a line
props.put("mail.pop3.apop.enable","true");
I still get Authentication Failure as shown below

I even tried to connect to POP3 (with SPA enabled) using telnet, there it shows AUTH as NTLM. Does this mean I have to use NTLM for POP3 to connect to Win 2003 POP3 (SPA enabled)? If I have to do so, which libraries to use?

Can anyone please provide any help in this regard?
