An email system using keys to open the server to receive messages. A message is created on a client, along with a request for the server to accept the message. The server will not even accept the message, unless the key is received. The key may be validated on many different levels of security; including length, or encryption code, or mathematical calculation. If the key is validated, the message can be received, either immediately, or later via a session code. |

1. An e-mail method operating on a computer, comprising:
on a computer, receiving only a request from an e-mail sender, where the request does not include a message part of an email, and where the request indicates that an email sender is requesting to send the message part of the e-mail, that is separate from the request; using said computer for verifying said request by determining if said request is a result of properly making a calculation on a remote computer and that said calculation on said remote computer is not a calculation that was previously verified, said verifying carried out by said computer, prior to receiving said message part of the email; only if said request is verified, producing a key using said computer, that is used to automatically receive said message part, where said key is only valid for a limited period, but is valid for more than a period of a single email, and where said key allows multiple messages to be automatically received without requiring said verifying to be carried out, only during said period during which the key is valid; using said computer for preventing the message part of the email, other than the request, from being received if said request is not verified; and if said request is verified, receiving multiple messages from said email sender, but only during said limited period while said key is valid. |
