on the other hand adding a regexp to the list spam filter is pretty simple. Is it 100% the best solution probably not, is it the best we can do with the tooling we have probably.
You do know that you are allowed to run more than one tool in a chain? If email comes in for a list, it can be funneled to a socket where a tool can check the Regex for special processing instead of calling SA. SA can be called on other messages, but can be avoided for messages meeting any other criteria.
I don't think anyone has suggested it isn't possible, at most that it requires more effort than it's probably worth. If you want to write a milter for postfix for this, I'll be happy to install and configure it. -- Per Jessen, Zürich (23.4°C) Member, openSUSE Heroes
