All your mails now end up in quarantine, which is a pitty (I release them, but it's annoying).  https://help.ubuntu.com/community/Postfix/DKIM#Configuration has things documented well it seems ;-).

Please could you be more specific? What exactly are you saying is
misconfigured? What do you mean exactly by "disable DKIM for
lists.ubuntu.com"? I don't think the list software adds DKIM headers.
Isn't that up to the original sender? So I don't understand what public
key you'd expect to add where.
