[Users] how can I change the 'read' status for an offline cached IMAP mailbox ?

[Cristian Secară]

I have a disaffected e-mail account, still available in the local imapcache directory, where some messages are left in "unread" status. How can I change the status for all cached messages to "read", as log as the remote mailbox is no longer accessible ? (i.e. editing some file in the local Claws Mail user directory)
