Hello, I should not have used this list as an example :) because it undermined my point.

In that light, DKIM, SPF and DMARC are of interest to any mail flow. What I am asking is if the option to place the sender in Reply-To: and have the list address in From: so it matches the SPF domain and so even DKIM could be signed by the list would be considered a good or bad idea by admins running lists.
