I would much rather get this than silent discard. At least when I've seen things in the logs in the past (yes, I do read my server logs), I have been able to follow up and fix them. I get the sense that Google is even going beyond using 550 and discarding email silently. I just did a grep through my logs to see if this message came up and found it nowhere, yet I have users on my mailing lists claiming they don't get emails and they've checked their spam folders. They're on GMail.
