pretty simple. normally if you send an e-mail to someone, he or she receives it disturbingly fast. well, most of the time. here at mailtothefuture.org you can tell the message to wait for some time before being delivered. that way you can set the message to be delivered some days later, or even years from now. nope. sorry. we are working on it but no luck so far. your message won't be delivered. it's much likely that you will receive a 'mail cannot be delivered' message from some mail server. you don't have a separate mailbox here. if you have a reply to some of your e-mails then it will be delivered to your original mailbox.
