I knew about the new postfix logging, but I tested this back when 3.9 came out, and I swear the old regex worked with it. But yeah, I just checked again and it doesn't. Maybe we broke it somewhere in between, as we were missing the test for the new logging - thanks for that!

Current versions of Postfix also attach details about the key-exchange, server-signature and server-digest to the header, causing the plugin to display 'unencrypted' on TLS 1.3 messages.
This PR adds an additional test case for those messages and fixes the regex to work for Stalwart, Postfix TLS 1.2, Postfix TLS 1.3 (old test) and this new Postfix TLS 1.3 syntax.
