I've setup IMC to email alerts using TLS1.2. When testing the email uses TLS1.3, see below. But when I get email alerts for device down/up the email alerts do not use TLS at all. As this is a global email setting I don't understand why/how the alert emails do not use the global email settings which include TLS.
Can anyone throw any light on this? Is there another setting in the IMC portal that controls critical device alerts?
ESMTP with both STARTTLS and AUTH (version=TLSv1.3
