Call <RFC2822From:RFC821MAILFROM> Sender-ID, and this would
provide a lightweight method that would curtail spoofing, spam, and allow
accreditation.
I meant to say <RFC2822_From : RFC2821_EHLO> could be called Sender-ID.
This would identify the sender with the channel, assuming the EHLO domain
was authenticated and was authorized. This would stop spoofing, phishing
and allow accreditation. It would not impact the way mail is used, nor
break anything. Unlike the current definition, this could abate spam.
