>From what I understand everything is okay here. For user.scottrus only the
size of the mailbox is shown, no quota is shown because it is set to -1 in
the quota db. I think the problem is that the quota file (assuming you are
using quota legacy db) is not removed when setting quota to none, instead
the quota is set to -1. quota -f reports for every used who has a quota
file, but correctly shows no quota for it.

What exactly do you consider broken here?
