Can't Delete An Unused Domain

[will]

When deleting an unused domain, with no apps, and email turned off, it errors simply saying "conflict"

@will This is most likely because there are mailboxes in the domain. Please delete the mailboxes (Email -> Select the domain in the dropdown selector and then delete mailboxes/lists) first.

The error message has been fixed for the next release.
