Add support for new TLS protocol settings syntax in Postfix
Is your feature request related to a problem? Please describe. The way Postfix defines a list of supported protocol versions in its settings in the current stable version (3.5) is via an exhaustive list of exclusions that looks like this:
smtp_tls_mandatory_protocols = !SSLv2, !SSLv3, !TLSv1, !TLSv1.1
The current experimental version of Postfix (3.6) adds a new, simpler syntax which allows users to specify the bounds like this:
smtp_tls_mandatory_protocols = >=TLSv1.2
Describe the solution you'd like
The Postfix settings file used by mailcow (main.cf) should be updated to use the new syntax once the Postfix Docker image starts being built with Postfix 3.6 or later.
Additional context Postfix 3.6 has not been released as stable yet and likely won't be included in Debian until Debian 11 at the earliest, so this issue is only meant to keep track of a change that should be made once the requirements for it have been met later down the road.

We'll change that when Bookworm is released and we change the os basics.
