setting up mailman2 and public-inbox

[Luke Kenneth Casson Leighton <lkcl@lkcl.net>]

eric, hi,

we're having difficulty understanding how to deploy public-inbox in a
way that very simply and as a top and only priority records email in a
public inbox, for the purposes of having it in a git repository, when
that email is coming in via exim4 and going into mailman2.

this really cannot be difficult.

we do not want to replace mailman2: its front-end, the subscription
capabilities, the user management are perfect and protect against
spammers, keeping the list clean.

we do not want to replace the pipermail archives at this point,
although that may be something we could consider at a later date.

the *only* thing that we want public-inbox for - right now - is its
ability to store the list email - *after* processing and acceptance by
mailman - in a git-backed repository, so that people in offline
situations have full and complete access to the archives.

how *exactly* do we do that one thing and one thing only?

(basically, if public-inbox accepted mbox format we could do what we
need, straight away.  the conversion process and the extra CPU time is
not a problem, because we already have to accept that overhead on
conversion, and the lists each month are not that big: 700 messages or
so).

are we missing something really simple?

if we subscribe a local user on the server (inbox@libre-riscv.org) to
the actual list, then configure that local account to have mail
delivered Maildir format, would that do the trick?

tia,
