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

Subject: [stunnel-users] JHH re: Server down?
Hi ..
I have been having spotty access to my main ISP email account the last two days so I
upgraded to latest sTunnel v 5.36.
I use sTunnel to help get emails from my ISP, Comcast, to load into an older version of GoldMine CRM.
sTunnel has worked like a charm since 09/2013.
In restarting sTunnel I immediately got a ‘server down’ error, log included below.
Ideas? Suggestions?
