Comment 4 for bug 1325568

OK. I see that your intent is different from that of the from_is_list feature which is solely intended for mitigation of bounce issues when a post is From: a domain that publishes a DMARC p=reject policy.

However, the whole point of the anonymous_list feature in Mailman is to allow a list where the poster is not identified. The need for such arises for example with a list intended for posting anonymous complaints or a list offering support for victims of domestic violence.

I think I understand your desire to identify the poster, even with only a list pseudnym, while completely removing the poster's email address, but I don't see it having enough general interest to warrant the additional configuration complication.
