Output did not contain fingerprint if smtp_tls_fingerprint_digest is not set

[jnandreae]

Starting with postfix 3.6 the default digest setting is changed. Default is now:

postconf -h -p smtp_tls_fingerprint_digest
${{$compatibility_level} <level {3.6} ? {md5} : {sha256}}

This is not working with the script. After setting the smtp_tls_fingerprint_digest = sha256 the main.cf the output is sha256 and working.

Can you please elaborate exactly what the issue is?

The output of postconf is different as expected by the program. Only md5 or sha256 are working but the return value is ${{$compatibility_level} <level {3.6} ? {md5} : {sha256}}
