ESA SMTP TLS

[cyberurmel]

Hello there, 

just perhaps a few simple questions for the professionals - could you be so kind to answer ? 

Mailsettings at moment : 

TLS 1.1  1.2 preferred for in and outbound 

questions : 

- anyone know when 1.3 is offered in ESA

- can i see how much from the incoming are using 1.1 instead of 1.2? 

i only find encrypted in summary . 

is it useful or best practices currently to disable 1.1 and set expected instead of preferred? 

thanks a lot 

Regards

The last roadmap I saw said 2H2023 (fiscal year, so... Aug?) They know that reporting on TLS1.1/1.2 etc. is weak, and more detailed reporting is coming, probably same time frame..
In the mean time you can look at your mail logs, they have the detail you're looking for.
I would check your logs for the past 6months... if no-one is using TLS1.1, you're probably safe turning it off...
