strange folders appearing on IMAP server
Over the past couple of months I have had folders with names like 'nfs000000000c8133a7000000b5' appearing on the top level of my IMAP server. They have appeared once or so per week and I now have 15 - all with names starting 'nfs000000000.....'
They cannot be deleted - i get the error message "This mailbox "nfs000000000c8133a7000000b5" could not be deleted. The IMAP command "DELETE" failed with server error: Mailbox does not exist, or must be subscribed to ..."
- which I am guessing suggests the problem is on the Mail application side rather than server side.
any ideas how to solve this??
thanks
