    I am currently pulling my hair out, trying to get this to work... Lemme
    show you a cyradm session, with some carriage returns thrown in for
    reading ease:

    Incidentally, we're running "unixhierarchysep: yes".

    localhost> ls -l /var/mail/c/user/calvizio
    -rw-r--r-- 1 cyrus mail 1911537 2007-09-07 02:43 1.
    -rw-r--r-- 1 cyrus mail 3717492 2007-09-07 02:43 2.
    -rw-r--r-- 1 cyrus mail 6364 2007-09-07 02:43 3.
    -rw------- 1 cyrus mail 32252 2007-09-14 11:52 cyrus.cache
    -rw------- 1 cyrus mail 183 2007-09-14 12:32 cyrus.header
    -rw------- 1 cyrus mail 1636 2007-09-14 11:52 cyrus.index

    localhost> lam user/calvizio*
    user/calvizio:
       cyrus lrswipcda
       calvizio lrswipcda
    user/calvizio/INBOX:
       cyrus lrswipcda
       calvizio lrswipcda

    localhost> cm user/calvizio/INBOX
    createmailbox: Mailbox already exists

    localhost> sam user/calvizio cyrus all

    localhost> sam user/calvizio/INBOX cyrus all
    setaclmailbox: cyrus: lrswipcda: System I/O error

    localhost> reconstruct user/calvizio

    localhost> reconstruct user/calvizio/INBOX
    reconstruct: System I/O error

    localhost> cm user/calvizio/INBOX
    createmailbox: Mailbox already exists

    localhost> dm user/calvizio/INBOX
    deletemailbox: System I/O error

    AGH.... I tried actually creating the dirs in the file system to match,
    and re-owning them to cyrus:mail, to no avail.

    Furthermore, ONE of the time I tried to create the mailbox, I typed "cm
    INBOX" instead of "cm user/calvizio/INBOX" by mistake, and now I have this
    wacko little mailbox called "INBOX" at the top of everything:

    localhost> lm
    INBOX (\HasNoChildren)

    I can't seem to delete this little monster either....

    Any ideas?

    Thanks,

    Rick Kunkel
