Hi All - doing: select status from message_queue group by status gives me 3 values: sent pending failed Are these 3 values the only value "allowed" in this field? Or, putting it another way, if messages are added to the table with a different status value would it cause problems in Koha? The reason I'm asking is: as soon a book with a reservation is returned on our selfcheck machines an email is added to the message_queue table with the status of pending. A lot can happen to this book before it actually gets on the reserve shelf, and may never actually get to the reserve shelf. If the book does go missing, gets hidden etc, the user with the reservation still gets an email telling them that the book is ready to collect (when it's not). To avoid this we are wondering if could stop this email from being sent (we only send out email notices once a day). We could delete the email from the message_queue table - I don't really like deleting stuff - or we could change the status. I guess I could change to "failed", but "cancelled" sounds better. I thinking of writing a bit of code to allow library staff to do this easily from the staff client - could I change the status to "cancelled" or is it better to stay with one of the original three?
