Though I hoped otherwise, I'm not surprised to see this answer.

OK, it may be USED by mailing lists, but (according to RFC822) not
for the PURPOSE for which "Revised LISTSERV" uses it.
But if Internet mail contains addresses like <...-request@...> or
<owner-...@...> in the "Sender:" header to indicate the item comes
from an MLM, that to me doesn't ensure that those addresses will
consistently reflect the relevant mailing list. In other words, if
the "Sender:"-addr is:
<OWNER-listname@somewhere> or <listname-REQUEST@somewhere>
will the following ALWAYS be true?
<listname@somewhere>
or could it also be:
<[log in to unmask]>
or worse yet:
<[log in to unmask]>
And besides <OWNER-..@..> and <..-REQUEST@..>, are there any other
such words that have the same ("guaranteed") behaviour?
Recently I've seen items from some "Revised LISTSERV"s which have
"X-List:" headers, and that header-line has up to now consistently
displayed the relevant and correct list-address itself.
Do I sense an intention to use (and advertise using) that header for
that SINGLE purpose? If so, how does one ensure that that header
will only be used for THAT purpose?
Regards.
