dkim-adsp is not in the email authentication result name registry 
defined in RFC 5451.  That's why x-dkim-adsp is used in the latest 
version of dkim-milter.  The "x-" denotes that x-dkim-adsp is for 
private use as it doesn't have a registration.

I won't recommend not signing the "Subject" header.

You can use the "z=" tag to reconstruct the "Subject" header.  Some 
mailing lists also modify the body of the message.  You could use the 
"l=" tag if the lines have been appended to get back the original 
body that was signed.
