Right. Approximately every mailing list in the world has this problem. >How to improve this? There is no good answer. If your system is fairly small, make a whitelist of mailing lists (probably by IP) and skip the DMARC checks. Some lists apply ARC headers which let you look back and see what the DMARC result was before the list changed it, but most lists don't, and at this point there is no ARC milter I would want to use.
