Yes, but this is just an additional check that's enabled when submit_user != NULL. If it wasn't checked, there would be no difference between a submit_user and a master_user. So might as well call it master_user and add a submit-flag to enable this extra restriction.

I know authentication user would be a pretty horrible name. That's why I named it master user, because I couldn't think of anything better :)

But I guess at least in wiki there should be more talk about "master user" not being the same as "admin user". There is actually already a check in imap-quota plugin that allows admin user to get quota for other users. This is checked from struct mail_user.admin boolean. Nothing ever sets that flag though..
