Just wanted to send this again with a clarified subject. Still getting the connect_blocking error. Any more ideas?
Thanks for replying, Brian.

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.
Here's the log after adding the above and trying to send another email.

From: Stephen Gates [mailto:[email protected]] Sent: Wednesday, June 26, 2013 2:25 PM To: '[email protected]' Subject: Sending Email from PLC Without Authentication with gmail
A customer needs to send emails from a Programmable Logic Controller (PLC) which cannot provide authentication. The customer's email server is gmail which obviously requires authentication.
The PLC IP is 192.168.1.2 and the PC IP on which stunnel is installed is 192.168.1.31
My config is:
cert = stunnel.pem
[smtps]
client = yes
accept = 25
connect = smtp.gmail.com:465
The PLC is set up to send emails to the IP of the PC 192.168.1.31
When I try to send emails I get the following in the stunnel log:
2013.06.26 14:26:30 LOG5[12384:13048]: Service [smtps] accepted connection from 192.168.1.2:2938

2013.06.26 14:26:30 LOG5[12384:13048]: Service [smtps] connected remote server from 192.168.1.31:53599
Any help would be greatly appreciated!
