Ooof!  That would be a massive misconfiguration.   Also, you'd be 
treating the symptom, not the problem.

As an alternative, why not simply set the reply-to address on the mass 
e-mail to a specific return address.  That way, bounces would go into 
that box and someone could go through and prune out addresses from their 
list so they won't even get attempted the next time.   Simply set that 
as a POP account and fetch all the messages out without leaving a copy 
on the server.

That way your server will receive the NDRs which could be used by the 
sender and it won't be replying to the NDRs that a box is full.

Also, you may want to have that organization consider an alternative 
such as using Mailman or even a 3rd party mailing list rather than 
copy/pasting a giant list of addresses in the "To" field of an email. 
It is, after all, 2018.
