Hi All,

For anyone who has looked into credit card PCI Compliance, you'll know what 
I'm dealing with.  But I'm trying to work with some pretty old systems.

To be compliant I need to disable SSL2.0 so I was trying to see if I could 
do it server-wide.  My first thought was to recompile openssl with --no-ssl2 
but that seems to only disable it for the tools rather than the linked 

After that, I gave up and started configuring programs one by one. However, 
despite my best ability to check, I can't see a way to disable SSL2.0 in 
Stunnel v3.X.

Anyway, I'll likely upgrade to 4.X but I'm interested if anyone knows the 
fix either for openSSL or Stunnel 3.X.
