The Mailman 2 list that I am considering importing into Discourse has had (for part of its existence) from_is_list set to Munge From, so that the “From:” header is
From: Listname <listname-bounces@listdomain.com> On Behalf Of [Original sender's name]
instead of
From: [Original sender's name] <username@example.com>
This made me think the importer would import each of these messages as if from the same user (with email address listname-bounces@listdomain.com)… BUT…
The initial line marking the beginning of a new email in the mbox file still begins with
From username@example.com [Date time group]
(and the Hyperkitty archives show the original sender’s email address as normal also).
So my question is – does the importer script take the sender’s address from the “From:” header or the "From " line? Thank you.
I discussed this briefly in a previous topic: Working on a mailman2 to discourse migration script - #10 by dachary
