You might want to also fix the DKIM_SIGN_HEADERS macro in the Exim config, as its default is currently broken (see #939808). The patch attached there is not helpful for local usage, so you might want something like what I've got in my config: ,--- exim4.conf --- […] # The default headers to sign is broken, and includes things that should # not be signed by default if they are missing, or they will break mailing # lists.
