That will work, if your users' mail clients handle rejection properly. Many
don't, and it's often better to bounce than to reject at SMTP time when you
know that the sender is a locally authenticated user. We only reject at
SMTP time on our MSA when we can't authenticate the user, or when they're
using an undeliverable or forbidden sender address.
