When somebody sends mail to your Sneakemail address it will first be sent to the Sneakemail system that will reroute it to your real address. They need to be be rewritten so that when you reply the email will be sent back to the Sneakemail servers first so they can continue to hide your identity. Although Sneakemail has many useful features that you will soon discover, its power can be demonstrated in the simple deletion of a Sneakemail address. If you feel that a Sneakemail address is being abused in any way you will have the ability to dispose of it and never receive email though it again. Email sent to it will be immediately annihilated by the Sneakemail servers and never bother you.
Deletion is only the final solution.
Another userful feature is evident if you're careful to create a new Sneakemail address for each contact you make. When spam starts appearing you will know exactly who has given out, loaned, or sold your address. It will be like a finger pointing right at them, or like DNA evidence. Perhaps online businesses and spammers will develop more respect for the Sneakemail address than for the regular kind and treat it better.
