I always use "local_header_rewrite_clients =". so postfix don't correct
users faults. Let everyone inject wellformated messages...

so far: postfix-2.9.4, opendkim-2.6.7

telnet postfix 25
Trying 127.0.0.1...
Connected to postfix.
Escape character is '^]'.
220 postfix ESMTP
EHLO x.y
250-postfix
250-PIPELINING
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

250 2.1.0 Ok
rcpt to: <you_at_example.org>
250 2.1.5 Ok

250 2.0.0 Ok: queued as 3YBDhR2qDFz3n8r

-> that mail is unsigned. But I do not see any warning from opendkim
that the message cannot be signed without a From header

I don't think that the order relay matters.
