A networking instructor on campus generously showed his students how to send mail from spoofed addresses from within our system. Told them not to do it, but of course they are. (Honestly though, some of them would have figured it out for themselves.)
I am set to relay only for two specific subnets on our campus. Other security items checked are "Auto-deny possible hack attempts" and "Disable SMTP VRFY command". Everything else is unchecked. Is there a way to verify local addresses only and still accept outside incoming mail? What might be my best options? Thanks for any suggestions.
