RE: [ietf-dkim] Delegated signatures in real life

Orbitz might not care about the security issues raised by allowing doubleclick to sign messages on behalf of their CEO and other executives. Many others will.

Actually, Doubleclick signs for email.orbitz.com, which is not the domain where the execs have their addresses. If there is some security problem here, you'll have to explain more clearly what it is.

This is a security area spec, least privilege must apply wherever possible.

Sure, but don't forget that the D in DKIM stands for Domain. The granularity is domains, not mailboxes. If you want per-mailbox signatures, DKIM isn't what you're looking for.
