If you have a catch-all address, and something gets delivered to it ...
who looks at it and fishes it out and sends it to the righ
his a plan, which that would force all the servers to
clean up their act.

No! Even though you don't have to have a mailbox to fill up (you can
direct catch-all to /dev/null

Spammers. ¯\_(ツ)_/¯ It serves both to verify operations of your server
