Chris, my entire point here is to not mix up the issues of DKIM/SPF checks on 
receipt and the issue of how the From: field is used.

No mail has been rejected due to changes to the From: field.

Some mail has been rejected because it doesn't pass DKIM/SPF checks.  When 
someone's mail is rejected due to DKIM/SPF failures then I'm happy to help 
diagnose that problem.  But it's not related to mailing list changes.
