The FILE distribution mechanism of LISTSERV almost works
like "internet distribution lists". Sites that run LISTSEND
or something create messages that contain NO indication
about the originator. The just come from LISTSERV.
 
What about implementing an option for a list to specify that mail
that arrives for the list with be just "prepended" by one
received line from each listserv on the distribute path etc. On
the last LISTSERV, i.e. at the place where the mail is given to a
mailer, the SMTP MAIL FROM: should be set to the address that is
supposed to get errors messages for this list or peer.
 
Using this feature for some highly "network internal lists"
on experimental base would eventually show benefits and
disadvantadges. With network internal lists I mean lists
like DEAR-BOD, EARNTECH etc.
 
I do not know whether this feature requires that all listservs
need an upgrade. If so, sorry for bothering you all.
