Such a rule does not cause bounces to be rejected at the protocol level.

Very true. If the MTA handling mail for the intended recipient accepts
the message for delivery then that's all that the sending host needs to
worry about, as is defined in the SMTP protocol standard.

If root doesn't receive messages then block _all_ messages to root
regardless of what sender address they arrive with (e.g. if they're not
delivered by a command-line agent running on the localhost).
