Hey everyone,
I wrote a milter library for PHP, because I wanted to create a bunch of different milter filters in PHP. I thought maybe others would be interested as well, so I published the library here: https://gitlab.com/noumenia/libmilterphp It supports all of milter protocol version 2. Its coded for PHP 7.2 up to and including PHP 8.2. I'm using it with Postfix 3.5 (AlmaLinux 8.7). Thank you.
