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?
