> 3. alignment domain-list value to include in alignment check:It doesn't scale as a complete solution for mailing lists. I don't see any scaling problem for the case of a domain used by a single entity that wants to authorize a few service providers to send email on its behalf.
Is that really a problem? I was under the impression that a sender either adds the providers' IPs to their SPF record, or gives them a DKIM signing key. This seems quite different from the mailing list problem, where it's unlikely that it is practical to track exactly which lists its users subscribe to.
