No, it does not. An auto-reply message, even if it is actually read by
the sender, can be ignored without penalty. An MTA rejection puts the
ball into the sender's court because the message has never been accepted
by the recipient's MX. By the way, a rejection is "legally safe", while
your catch-all-and-let-messages-rot approach is not, in case you have
not considered that.

Of course, you can do as you please, but that does not change the facts
and mechanics involved.
