When did inbound start using TLS 1.3?
Hello,
Today I received notice from our inbound mail filter that the mail filter is getting connection errors for TLS1.3
They say this start today at around 7:00AM CST.
When would cPanel have started using TLS1.3? I looked we have TLS1.2 set for inbound with no option for TLS1.3
cPanel Version 116.0.11
I see errors in log like this:
2024-01-28 03:50:16 TLS error on connection from [IP address]:49337 SSL_accept: TCP connection closed by peer

Hey there! The short answer is, we don't - tls 1.2 is still the minimum protocol setting available in WHM >> Mailserver configuration, and as you found, there is no option for 1.3.
Do you have any additional details related to the connection error you're seeing?

Ho there! Hi there!
At this point the issue TLS errors and peer closed connections have stopped after rebooting the server for other reasons.

Even better!
