Yes, it would work. This will not block email sent to
never_been_a_valid_emaildomain.com, so you system would generate a bounce
for those.

A better way is to tell postfix what the valid recipients are.

If the addresses are local (nor virtual), then using local_recipient_maps.

If the addresses are to be relayed to another server, then
relay_recipient_maps would be the way to go.

Good luck,
