DMARC is increasingly being used as a spamfilter, checking whether the sender ought to send mail via this route. To comply with this for mail sent through Mailman, we will change the From: sender address to the list address. The current: > From: Some User <some.user@somewhere.domain> > Sender: "listname" <listname-bounces@science.ru.nl> will be changed to: > From: Some User via listname <listname@science.ru.nl> > Reply-To: Some User <some.user@somewhere.domain> > Sender: "listname" <listname-bounces@science.ru.nl>...
