Surendra: 

1. If I use GSSAPI, how it can resolve these issues? COuld you please let me know the steps to clarify the same? Any pointers on this is appreciated very well. How Server Authentication happens with GSSAPI? How does Service Ticket transferred?

2. What kind of implamentation should be done at ESMTP client side to handle the Kerberised ESMTP Server response?
