I don't care about backscatter.  There's no reason anyone should see
significant backscatter these days; it's pretty much a solved problem.

(watermark all outgoing email and look for that watermark on DSN reports)

In any event, for this specific case I do already reject the user "at
the gates".  But I want to reject internal email for folks that don't
know that user account has gone away.  I prefer not to do it in the MTA
so as to keep the MTA as free from this type of configuration that
lingers for years and makes future migrations difficult.
