Email most secure setings

nicfab

I set my account email with port 993 SSL and 587 SSL.
From the email configuration, I see the opportunity to set the Encryption policy as “Enforce TLS incoming” and “Enforce TLS outcoming”, as in the image below.

Activating them, should I have more secure email settings?
Is there anyone who can clarify it?

“More secure” yes, but you probably won’t be able to send or receive mails from some older or misconfigured servers out there.
You could try it out and watch the postfix logs for some time which servers cause an error due to do not fulfilling TLS requirements.
