Giving the different prefix a try on a test account, a mailbox directory is created, but the rest of the maidir directories (new, cur, tmp) aren't created, and the error below is returned.

The key is the message "Error: user test at sharp.fm: Initialization failed: namespace configuration error: There can be only one namespace with inbox=yes"

I have two namespaces defined, I am assuming this is wrong:

namespace inbox {
  inbox = yes
  mailbox Trash {
    auto = subscribe
    special_use = \Trash
  }
  mailbox Drafts {
    auto = subscribe
    special_use = \Drafts
  }
  mailbox Sent {
    auto = subscribe # autocreate and autosubscribe the Sent mailbox
    special_use = \Sent
  }
  mailbox "Sent Messages" {
    auto = no
    special_use = \Sent
  }
  mailbox Junk {
    auto = create # autocreate Spam, but don't autosubscribe
    special_use = \Junk
  }
  mailbox virtual/All { # if you have a virtual "All messages" mailbox 
    auto = no
    special_use = \All
  }
}

namespace {
  type = private
  separator = .
  prefix = INBOX.
  inbox = yes
}

Graham
