I just posted from a Yahoo account, but I don't think that's the issue: 
the problem, if I understand it, is that other subscribers to this list 
who have gmail, hotmail, etc., accounts where /their/ ISP enforces DMARC 
/will/ /not/ /see/ my post, because *their* email server will reject my 
email, since the Mailman robot modifies the "Subject" line and does 
other things that break DMARC. Someone correct me if I've got that wrong ...
