Dear #Letsencrypt, you helped secure millions and millions of servers, not just web servers. But your announcement at https://letsencrypt.org/2025/05/14/ending-tls-client-authentication/ about ending Ending TLS Client Authentication Certificate Support in 2026 because Google changes their requirements would result in your certificates being unusable for SMTP servers. You are literally risking an email collapse for many mailserver owners just to please Google? Please think again. Please.

@jwildeboer are you really using the tls client authentication in your smtp server? Haven't seen that in a while.
And if I'm reading it correctly, they still support it. But you need to request separate certificates. Which isn't too bad. -

Which isn't too bad.@antondollmaier @jwildeboer only until May 2026: "May 13, 2026: the tlsclient ACME profile will no longer be available and no further certificates with the Client Authentication EKU will be issued."
