localuser_dkim:
         driver = manualroute
         domains = +local_dkim_domains
         condition = "${if def:header_DKIM-Signature: {no}{yes}}"
         headers_add = X-DKIM-debug: seen by localuser_dkim
         transport = remote_smtp_dkim
         route_list = * 127.0.0.1

I have this router now, but when triggered it throws me a temporary error "remote host address is the local host", which is the whole idea to force a dkim signature to the mail. I guess the local host issue is a protection against looping, but in this case it is wanted and taken care to take a single round only. How can I convince/force exim to allow this?
