Riposte solution
An APPEND command failed— the message was not saved to the mailbox. This could be due to a server error or quota issue. If you're trying to save a message via Riposte (like uploading an email or saving a draft) and get this, you should attempt the operation again or save it to an alternate folder. Check for any server alert (like quota) that came with this and address that (free space or try later).
