Good Question.
The RFC purist in me says, hell no. But my calmer, gentler, experience
mail inner child would say you should work to extend your edge so you
decline the message during the SMTP conversation if at all possible.
Backscatter, joe jobs, and bounces with payloads/spam have pretty much
ruined bounce messages IMO.

Bounces coming from blank envelope senders are being held to SPF/DKIM
authentication, which of course fails. Been seeing this a lot lately.
Should we just not send bounce emails to Google anymore?
