Re: [stunnel-users] Sending Email from PLC Without Authentication - With debug = 7 log
Just wanted to send this again with a clarified subject. Still getting the connect_blocking error. Any more ideas? Thanks for replying, Brian. From: Stephen Gates [mailto:sgates@hkscholz.com] Sent: Wednesday, June 26, 2013 3:09 PM To: 'stunnel-users@stunnel.org' Subject: RE: Sending Email from PLC Without Authentication with gmail I added the following as Brian suggested. debug = 7 I tried doing output = stunnel.log but that cause an error when I reloded the config file.
