But..
IF you *really* mean not just an easily forged / accidentally mis-configured
'From:' address, but actual 'company assigned' staff e-mail accounts,
THEN
you may be better served to limit that destination to traffic from
locally-authenticated submitters. E.G. - even if/as/when traveling, your staff
can be submitting & authenticated, via port 587 to your own server.
