Hi,
I didn't changed anything in Postfix configuration. But yes, over the
last months, we upgraded from Debian 11 (OpenSSL 1.1.1n) to Debian 12
(OpenSSL 3.0.9).
I don't see anything in openssl.cnf that could restrict something, if
you have any idea.
Best regards,
Camille

Did you change the default TLS settings (of postfix), e.g.,
made any restrictions?
Or did you recently upgrade to OpenSSL 3 (which loads a default
openssl.cnf file which probably changes the defaults)?
