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]: connect_blocking: connected

server from 192.168.1.31:53599

 

Any help would be greatly appreciated!
