Naturally the people who can't read RFC5322 and understand that the From
header line represents the writer of the message also can't read RFC5321
and grasp that a 2xy code signifies a responsibility that is well defined
(sec 4.2.5).
They're just making stuff up. And companies that fall for it betray their
cluelessness.

(N.B. They were so proud of using "wherein" that they got lost later in the
sentence-- s/b "discards" not "discarding".)
