For actual spam, it doesn't matter if you /dev/null or 550 them. My point -- to the list, not really so much to you since I realize you have your own reasons -- was that there is a possibility of a legit sender's message hitting the threshold, and for that message, it is much better to 550 than /dev/null so they can figure it out. It's only for that very rare legit mail that it matters, in my view, but there it's important. Thus, I have a setup to MTA-reject at 8 and everything that makes it through that gets filed, in INBOX if low enough, and in a spam folder if not.
