If you do not want replies or handle the bounces its BCP to use an empty 
envelope sender.
Save all parties a lot of noise.

Anything else is a waste of cycles, bandwidth and makes zero sense.

Of course, if you're sending mail to rcpts and its bouncing back, you 
shouldn't be sending it in the first place..
