broken mailbox

[Gerard Ceraso]

I don't know what I did but I think I broke one of my mail boxes. I cannot get to it from any of my mail browsers, this folder is pretty hefty though. I am using cyrus imap I believe version 1.5. I get this error when trying to rename it from cyradm. localhost> renm "INBOX.Debian Users" INBOX.DebianUsers command failed: Mailbox has an invalid format
