SMTP auth is only useful for SASLish stuff or <protocol> before SMTP relay
issues.  That doesn't stop 3rd party spoofing of 3rd party addresses.
Since that's the majority of mail into an organization (in my experience,
>90%), it's hardly effective.

Most *nix MTAs these days stop 3rd party relay of 1st party addresses (my
experiences with Notes as an MTA in the distant past make the
recommendation of a "real" MTA in front of it easy to advance.)
