Finally after a longer than expected approval process, FolderBuddy 1.3 has been approved by the AppStore review team. You can open view FolderBuddy in the now.
Version 1.3 is now available in the AppStore. The new version is adding one feature requested by many users : show how much space a particular account is using. This is done using the QUOTA command and the latest version will nicely display how much space your account is using on your server.
Please be aware that some IMAP server like Yahoo Mail! do not support the QUOTA command and thus FolderBuddy will not be able to get that information. Other services like MobileMe, GMail, AOL and many others do support it.
