I can confirm that the Cambridge group has the option to be subscribed but not get any mail. To quote our standard moderator message "After you have logged in, on the group webpage there is an "Edit Membership" option in the white bar towards the top of your screen (by your name). If you click there it lets you make changes to your email delivery."
