IMHO: If you want to avoid backscatter, you must disable the user in the MTA, in order to reject the message during "rcpt to" command or at least in DATA.
I don't care about backscatter.
You should - if you are a backscatter source, you *will* be blacklisted, sooner or later.
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)
Yes, that helps you avoid *other* people's backscatter, but that wasn't the point of the warning: don't accept-then-bounce. If you're going to bounce it later, reject it at smtp time.
