In a recent recent Rocky Linux update OpenSSL was upgraded from version 3.2 to version 3.5. This resulted in Postfix generating the following error:

postfix/amavis/smtp[10244]: warning: run-time library vs. compile-time header version mismatch: OpenSSL 3.5.0 may not be compatible with OpenSSL 3.2.0'

The end result is that mail is no longer accepted, postfix on 127.0.0.1 generates a 'Connection refused' error.

Is this a known problem? Is it possible to compile Postfix to support OpenSSL 3.5?
