Hello Paul,
I guess there is an other process listening on TCP port 25 and stunnel
service can not start now because there is a port conflict.
Try 'netstat -abn' in a command prompt window in a privilege elevated
session to identify this process. Then you can change this port number
to another free port in the stunnel configuration file.

Best regards,
