So does Exim fail to validate some DKIM signatures? Should I report a bug on their side? I'm not able to manually verify the maths behind those signatures, I have to rely on the MTA to do its job correctly.

I don't see any problem at all with DKIM from the list. (I'm not the person who implemented or configured it but) This list manager is well configured imho.
Please check your incoming emails coming from the list. They are not "forwarded" breaking DKIM or SPF but they are rewritten with a new valid DKIM signature. May be you have an intermediate incoming MTA that is breaking things at your side. This also explain why you are having issues with other mailing lists as well.

Hello,I'm having trouble receiving messages from this mailing list because many of them have a broken DKIM signature. I guess that's because the mailing list is not configured properly to survive in today's e-mail world. If a message with a DKIM signature is sent to this list (like mine), they're forwarded to all subscribers without correcting that signature but at the same time modifying
subject, body or sender.Maybe somebody would like to take a look at that to ensure that messages from this list can still
be delivered.This is an article I found about the topic, it might be helpful in fixing the problems.
https://begriffs.com/posts/2018-09-18-dmarc-mailing-list.htmlI'm writing to the list directly because list owners never seem to respond to such issues. Several
other mailing lists I'm subscribed to have the same issue.If you'd like me to read your reply, please CC me as well to make sure your message arrives here.
