But for actively maintained servers, could they not be configured to support TLS for clients that request it without breaking plaintext email for old clients? I'm trying to understand whether supporting old clients really means not supporting encryption features for up-to-date clients.
- walrus01 8y agoI was referring to server-to-server mail exchange. Yes, this is how my server is. When exchanging smtp with another domain's mx, if that other smtpd will not do TLS, it sends plaintext mail. For clients submitting mail via smtp with auth, such as thunderbird on my desktop PC, of course it does TLS1.2.
