Using JavaMail with ESMTP exchange server

Question

Hi all,
I have been looking at the FAQ, the SSLNotes.txt as well as the posted codes here and on google, but I am still having problem with the following scenario:
An exchange ESMTP server which gave me a "Unrecognized SSL message" exception when I enabled TLS and passing in an authenticator for login.
After experimenting with my IT manager, we concluded that the login has to be done in plain text after which TLS can then be switched to.
So can anyone be able to provide me with a sample code for accessing such a server or point me in a direction as to how to implement a solution for it?
Thank you very much in advance.
Best Regards,
James

Sorry for the extremely late reply to your post Shannon and thank you for your help so far. I was caught up with other tasks.
The following is the debug trace I managed to capture:

  nested exception is:
