I finally got around to testing this.  I tested with RC7 CSV 20060924.  And I am testing with just one namespace:

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

I no longer get the unknown namespace errors.  However, INBOX is listed twice in the LIST command:

2 list "" "*"
* LIST (\HasChildren) "." "INBOX"
* LIST (\HasChildren) "." "INBOX.RSS"
* LIST (\HasNoChildren) "." "INBOX.Sent"
* LIST (\HasNoChildren) "." "INBOX.Test"
* LIST (\HasNoChildren) "." "INBOX.spam"
* LIST (\HasNoChildren) "." "INBOX.Trash"
* LIST (\HasNoChildren) "." "INBOX.Drafts"
* LIST (\HasNoChildren) "." "INBOX"
* LIST (\HasNoChildren) "." "INBOX.RSS.Kevin Minnick"

If I change the namespace's inbox setting to "inbox = no" it only lists the INBOX once, however subscribing to the INBOX gives the "Unknown namespace." error.

2 list "" "*"
* LIST (\HasChildren) "." "INBOX"
* LIST (\HasChildren) "." "INBOX.RSS"
* LIST (\HasNoChildren) "." "INBOX.Sent"
* LIST (\HasNoChildren) "." "INBOX.Test"
* LIST (\HasNoChildren) "." "INBOX.spam"
* LIST (\HasNoChildren) "." "INBOX.Trash"
* LIST (\HasNoChildren) "." "INBOX.Drafts"
* LIST (\HasNoChildren) "." "INBOX.RSS.Kevin Minnick"
2 OK List completed.
4 subscribe INBOX
4 NO Unknown namespace.
