Handling mailing list "From" rewriting

[Arsen Arsenović]

Hi!

Many mailing lists (including this one, it'd seem) do "From"-rewriting,
where they transform the "From" header of a mailing address to name the
mailing list rather than the sender.

For instance, if the "From" header is

From: "Arsen Arsenović" <ar...@aarsen.me>

... and I am emailing Gcc-help (gcc-...@gcc.gnu.org), then Mailman will
rewrite the "From" header to be:

From: "Arsen Arsenović via Gcc-help" <gcc-...@gcc.gnu.org>

... before forwarding my email to subscribers.

This has two effects:

- 'mu' considers the name of "gcc-...@gcc.gnu.org" to be "Arsen
Arsenović via Gcc-help", and completes to that incorrect value
- Replying to this email cites "Arsen Arsenović via Gcc-help
<gcc-...@gcc.gnu.org>" rather than "Arsen Arsenović
<ar...@aarsen.me>", with the "To" header being the mailing list, and
the original sender being in "Cc"

Is there some good solution to this issue? Where good means reliable
and local?

Personally, unfortunately, I've failed to come up with one. I thought
it may be best to do some postprocessing in 'mu' relying on List-Id
headers, but List-Id doesn't necessarily correspond to where the email
comes from, it'd seem.

Thanks in advance, have a lovely day!
