Why is there such a recommendation? What is a mail receiver? I am
asking the question as there is "receiving SMTP server" in that sentence.
That would be silly. RFC5322.From might contain no DNS domain to begin with.
In Section 10.1:
"Have no RFC5322.From field (which is also forbidden under RFC 5322
[MAIL])"
Where is it stated in RFC 5322 that it is forbidden? That RFC
specifies a syntax for the Internet Message Format.
Some MTAs (sendmail?) seem to recreate an RFC5322.From from the Envelope,
in case that it is missing in the message.
