I did check the mailman source code and it does leave the
user name mostly untouched. So (presuming @example.com has
a DMARC 'reject' policy),
From: Some User <someu...@example.com>
would be changed to
From: Some User via users <users@lists.fedoraproject.org>

Maybe we'll be lucky and everyone will move off @yahoo.com,
giving the infrastructure team a nice present.
