 ARC is intended to support the utility of SPF and DKIM in the presence of
 intermediaries in the transmission path - forwarders and mailinglists -
 by establishing a cryptographically-signed chain in headers.

 an intermediary.  One might do verify for local destinations.
 
 ARC uses the notion of a "ADministrative Management Domain" (ADMD).
-Described in RFC 5598 (section 2.3), this is essentially the set of
-mail-handling systems that the mail transits.  A label should be chosen to
-identify the ADMD.  Messages should be ARC-verified on entry to the ADMD,
