ERROR : Could not complete request. Query: COPY 99:99 "INBOX.SPAM" Reason Given: [TRYCREATE] Mailbox doesn't exist: INBOX.SPAM

Running latest stable version of squirrelmail, dovecot, qmail and vpopmail with Maildir storage in virtual users.

One of my users reports seeing this yesterday, then it went away for a few hours, then early in the next day it happened again on the same account, but went away a little while after that.

Any idea what could be happening here?
