These footers break DKIM signatures. Therefore, the list can either

I think that other mailing lists (or software that do the same or
similar job) don't have such a problem (with DKIM signatures), because I
see that they have a footer (including unsubscribe).
So, maybe you should consider moving to some other mailing list software
that is more up to date.
All mailing list managers have this issue. If they put footers, you can
notice they are likely to mangle the From header for people with DKIM
signatures on their domain. The alternative is to remove signatures or
just ignore them and this is a recipe to categorized as spam.
If you ask me, I would suggest migrating the mailing lists to Discourse
(https://www.discourse.org/ <https://www.discourse.org/>), which is a
modern version of mailing lists.
I have some experience with installing and maintaining Discourse, and I
know how to make the migration from mailing lists to Discourse (I have
done it for FLOSSK a few years ago).
If anyone from the Debian infrastructure team would be interested to
discuss more details about this, I will be available during the DebCamp
and DebConf.
We had this discussion two years ago:
https://lists.debian.org/debian-project/2020/04/msg00074.html. I think
it went nowhere for the usual reasons (no opinion, just FI, so that you
know people you should get in touch with).
