    A few questions:

     

    1. where did you obtain the SSL certificate (self-signed, local certificate authority, third party certificate authority like verisign?

       

    2. Did you run ssldump against the tcpdump file you created?

       

    3. Do you have a virtual server on port 25? If so, are things working properly on that VS?
