[exim] Local DKIM signing

Hi all,

I know my request is usually not necessary, since a local MTA trusts itself, but I need to DKIM-sign messages that come from a local domain to a local domain.

My remote and local transports look like this and are working:

remote_smtp_dkim:
         driver = smtp
         dkim_canon = relaxed
         dkim_domain = fixed.dom
         dkim_private_key = /etc/exim4/dkim/fixed.dom-private.pem
         dkim_selector = key2023

local_delivery:
driver = appendfile
group = mail
mode = 0660
mode_fail_narrower = false
envelope_to_add = true
return_path_add = true
directory=${home}/Maildir
maildir_format = true

How can I change the local_delivery to sign a mail? Simply copying the dkim_ tags from remote to local tells me, option dkim_* unknown. I guess signing is not defined in local-delievery situations? But what can I do?
