Notications from "Anonymous" on Savannah not sent to mailing list

It looks like no notifications are sent to the mailing list when an “Anonymous” user opens a report on Savannah.
E.g., the original post of this report never made it to the mailing list (archive.

Does the configuration of the tracker on Savannah need changes (after the update to the never OS on the server)? Or is this something the Savannah admins would need to check?
