Right. Some clarification:
When signing mail using the current Exim DK implementation, adding
headers in either ACLs, Routers or transports is completely
uncritical, since signing is done while the message is leaving the
system (only eventual TLS encryption comes after DK signing).
When you forward DK-signed mail, you should not add headers after the
signature header. For headers added in ACLs, there is the mentioned
workaround. For headers added in routers or transports, there is no
workaround.
