You're right, Dave, in a narrow, technical sense. There is overlap in the
two approaches.
However, there is an hierarchy to the processing, and I'm pretty sure the
"SMTP clients" sending mail from trusted ip's are not challenged by SMTP
AUTH, so speeding up sending mail from trusted ip's.
But for operational reasons, it's simpler to tell all clients to use SMTP
AUTH even if they come in on trusted ip's.
Furthermore, for those of us that relay SMTP traffic for other servers, we
need a way to trust them without SMTP AUTH and relay for ip's is the way.
