[exim] Exim, DKIM and DomainKeys - possible?

Is it possible to set up Exim to sign outgoing emails with both DKIM and DomainKeys?

I've been trying for a while, but so far, I've been only able to sign the mail with either DKIM or DomainKeys, but never both.


With such setup, it adds DomainKeys signature:

dk_remote_smtp:
driver = smtp
interface = ...
helo_data = ...
dk_private_key = "/var/cpanel/domain_keys/private/${dk_domain}"
dk_canon = nofws
dk_selector = default

With this one, it adds DKIM:

dk_remote_smtp:
driver = smtp
interface = ...
helo_data = ...
dkim_domain = ${sender_address_domain}
dkim_selector = default
dkim_private_key = "/var/cpanel/domain_keys/private/${sender_address_domain}"


With this one, it only adds DomainKeys. I expected to have both signatures.

dk_remote_smtp:
driver = smtp
interface = ...
helo_data = ...
dkim_domain = ${sender_address_domain}
dkim_selector = default
dkim_private_key = "/var/cpanel/domain_keys/private/${sender_address_domain}"
dk_private_key = "/var/cpanel/domain_keys/private/${dk_domain}"
dk_canon = nofws
dk_selector = default


Is there anything else I have to set up to have both signatures included?
