Mailman has an option to drop the DKIM header which makes the email just go
unsigned - and this would surely fix.
Although, it doesn’t look particularly elegant to drop a signature - should
probably look into a way to re-sign outgoing email after all modifications are
done (subject, envelope from, etc).
UKNOF seems to be on Mythic Beasts and use their relays?
