Where are logs for SMTP SSL Failure?

I have a SHARP MX-M6070 printer that needs SMTP to email scanned documents.

If I set it up to not use SSL and just send emails over port 25 with authentication, things work. But if I try to enable SSL it fails (whether I use port 25 or port 465).

Our installation has exim v 4.93, fwiw.

I do not see any error messages in the /var/log/exim4/mainlog. Where can I find the SSL log for the failed SMTP attempts?

If anyone has ideas about how to better debug this issue, feel free to share them. :cowboy_hat_face:

Probally you need to downgrade ssl / tls on your server as it doesn’t support tls 1.2
