If you stop payment on a postdated cheque and the cheque is cashed by a maney mart before the date on the cheque are you responsible?
Looking at the two questions together, you may refuse the payment of a premature presentment of a check by telling your bank in writing ahead of time. The payee though may re-submit the check after it becomes due and then you are responsible. Because presenting a post-dated check early might be considered fraud, you might take them to small claims court and ask for treble damages caused by the overdraft.
