Your curl reports an SSL error, so you're using its native SSL support  
instead of stunnel client.

Remove all non-essential configuration file options.  If you don't  
understand an option, just leave it at its default instead of using a  
random value.

Collect stunnel debug logs on both ends.  Hopefully this will help you  
find the solution by yourself, without asking 536 subscribers of this  
mailing list for help.
