As DMARC protection, some mailing-lists (like postfix-users)
rewrite the "From:" header, with at least 2 drawbacks:
* This breaks e-mail searching by the "From:" address.
* At my work, only the address is changed (without introducing
"via <mailing-list>"), so that this is very confusing as mail
appears like
From: Firstname Lastname <mailing-list-address>
and we start seeing users sending private mail to mailing-lists
because they did not notice that the address changed.
I was wondering whether I could ask postfix to revert the "From:"
header back to the original value, just before the local delivery,
at least for lists that keep the original address in some other
header ("X-MailFrom:" for postfix-users, "X-Original-From:" for
some mailing-lists...). Any idea?
