John, Are you sure no other service is listening on localhost:995 ? Perhaps your previous stunnel installation in service mode? The error I see bind: Permission denied (WSAEACCES) (10013) may imply port already in use or that a winsock filter (antivirus) is blocking the socket opening. You may want to run tcpview.exe or netstat -anb (in a privilege elevated session) to see which process has the port locked. Regards,Jose
