Cain and Able is not the appropriate tool to sniff traffic, use ethereal.
Cain and Able is a very appropriate tool to spoof SSL connections to
unsuspecting users.  You have not turned on certificate
verification in your stunnel configuration file so from an stunnel point
of view that makes you an unsuspecting user.

1. I think you're being fooled by Cain and Able.
2. Don't use Cain and Able on a production machine.  Bad bad bad.
