Actually, DKIM makes no statement about authorship or even actors in the 
handling sequence.  It merely says that that verified domain is willing to take 
"some" responsibility for the message.

The more we slip into loose references to authorship or operational origins, the 
more we wind up having to dig ourselves out of semantic mismatches later.

If there is a desire and need to have the semantic be "came from the mailing 
list" then there needs to be a mailing list equivalent to ADSP, which correlates 
a DKIM signature with the domain in a List-ID header field.
