Roundcube displays diskusage per default and hovering over it displays detailed information. Thunderbird has an extension, Display quota. For both and others to actually work a file is required. This file will be created and updated whenever postfix delivers a message or when courier-imap makes changes. The file is located in each virtual users root mail dir, which would be in the case of  on. Thus sending a message to testuser@example.com would create this file in the users maildir.
