Hello R, I only wrote about the incoming side - of course, you also want 
to send mail to remote users, and that includes users with an address of 
…@myisp.com. They will go to the ISP and be fetched to local from there.

And if internet's down, e-mail will stop working anyways, so why bother? 
Even facebook/whatsupp will stop working then!

With some tinkering, you can configure your local relay smtp to deliver 
those locally, but if your people do not talk about their vacancies over 
the water cooler, then they will miss that reminder then.
