Hi,
I currently need to send mail through the IIoT library and it works well with GMail, but I can't get it to work with our mail server.
Monitoring Wireshark, I've successfully sent mails with our server using python smtplib. It uses TLSv1.2.
When I send email with the codesys library using our server, it uses TLSv1 and fails.
However, when I send mail with the codesys library using gmail, it uses TLSv1.2 and works.
Does anyone have a clue why the library automatically chooses TLSv1? Maybe I can change our server's setting. Also, we cannot remove TLSv1 due to other services.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Let me check, seems we mis a posibility to force the lib to use either TLS 1.1 or 1.2
