maybe, but the OP imho want to smtp auth ALL emails
All *outgoing emails only, from *all users irrespective of
whether they sending to local or non local domains.
Is there a way to achieve ?
This isn't possible without separating local mail submission
from general internet incoming mail.
Probably the easiest way to do that is to require your users
to submit mail on the submission port 587 or smtps port 465,
and use your firewall to block or redirect port 25 from your
local network. Then put whatever restrictions you want on the
submission port.
