Abstract:
In an E-mail protocol between a sender and a receiver, an intermediate server subscribed to by either the sender or receiver assures masking of the primary E-mail address of a subscriber in E-mail messages between sender and receiver. The protocol also archives all messages passing through the intermediate server for the subscribing sender and/or receiver by addressee.addresses.

CROSS-REFERENCES TO RELATED APPLICATIONS 
   This application claims priority from Provisional Patent Application Ser. No. 60/316,377, filed Aug. 30, 2001 entitled E-mail protocol using assumed send and reply address and smart E-mail archiving by addressee and addressor. This patent application is incorporated by reference as if fully set forth herein. 

   BACKGROUND OF THE INVENTION 
   This invention relates to E-mail. Specifically, the disclosed protocol uses an assumed E-mail address to mask and/or maintain confidential the specific address of a subscriber, so long as the sender or the receiver is system subscriber. 
   E-mail services are known under the common name of “remailers”, which enable messages to be sent with anonymity. Reply is a different matter. These services typically do not allow for reply on an anonymous basis. 
   Other so-called E-mail services are known which require access to a remote server site. Once the user is on the remote server site, massages are sent and received from that remote site. The reader will understand in reading what follows, the E-mail protocol proposed hereafter does not require access to the remote server site to send and receive messages. Rather, in the process that follows, where either the sender or the receiver of E-mail is a system subscriber, mail is forwarded by the disclosed protocol through an intermediate server. It is not required that the system subscriber logon to the intermediate server for message transmission to occur. 
   Finally, it is known in certain E-mail services—such as certain “match making” services—to maintain confidentiality of real E-mail addresses between E-mail corresponding parties. In these cases, both parties must belong to the same E-mail service. It is not possible for just one party to use the service and maintain the desired secrecy of their primary E-mail address. 
   The reader will understand that the discovery of a need can constitute invention. I have discovered that there is a need for an E-mail service where the sender, or the receiver of E-mail can have their primary E-mail address maintained confidential or assume a specific identity. A system subscriber can send and receive E-mails in a specific identity without logon to the system. In what follows I disclose such a protocol, which has the additional advantage of permitting smart archiving of incoming and outgoing E-mails in folders related to all E-mail correspondents of a subscriber. Smart archiving of previous or existing E-mails forwarded from other E-mail systems is also included. 
   In the Specification that follows I will refer to a subscriber&#39;s E-mail address as being the “primary E-mail address” of the user. Further, I will refer to the protocol as providing an “assumed E-mail address.” This assumed E-mail address is that E-mail address in the disclosed protocol to which sending and reply is encouraged; using the assumed E-mail address and the protocol here proposed, the primary E-mail address remains hidden or confidential. 
   Additionally, in the specification that follows I use the term “delimiter”. This is a term of the computer art, which is defined as A character or sequence of characters marking the beginning or end of a unit of data. Examples of such delimiter can include “@”, “.” (that is period), “%”, and other indicia commonly recognized by software as indicating the beginning or end of a unit of data. 
   BRIEF SUMMARY OF THE INVENTION 
   An E-mail protocol uses an assumed E-mail address to mask and/or maintain confidential the primary address of a subscriber, so long as the sender or the receiver is system subscriber. Messages have “to” and “from” addressing in the format (john02@university.edu) with a user identifier (e.g. john02), a delimiter, here in the form of a user identifier sign (e.g. @), and domain name in the format name type (e.g. university.edu). An assumed E-mail address consists of a user identifier sign, an intermediate server domain name and a user identifier, which can be different from the one in the primary E-mail address. 
   Presuming a subscriber (susan) wishes to send an E-mail to a non-subscribing party (john) for the first time, the delimiter and intermediate server domain name (e.g. @storagemail.com or “.storagemail.com”) is concatenated to the end of the receiver&#39;s original domain name before transmission. If user identifier sign (e.g. @ and intermediate server domain name are used, the receiver&#39; user identifier sign (@[which in reality is a delimiter] is substituted with another delimiter (e.g. %). This leaves the receiver&#39;s address in the format john02%university.edu@storagemail.com or john02@university.edu.storagemail.com. The E-mail is thus addressed to the intermediate server. Provision can be made for the substitution of the entire E-mail address. 
   Another way to view this address is to remember its format phrased in terms of “delimiters.” When this format is phrased in terms of delimiters, the format becomes: 
   john02[delimiter]university[delimiter]edu[delimiter]storagemail[delimiter]com[end of address]. It is not important to this invention what form of delimiter is used. Following the examples of this specification, many forms of delimiters can be utilized. It is only important that these delimiters when parsed by modern E-mail routing system end up addressed to the correct E-mail destination. 
   Upon receipt at the intermediate server, an archive folder is created with the receiver&#39;s E-mail address and a copy of the E-mail archived therein. The message is resent from the intermediate server to the intended receiver. 
   Upon resending, the sender&#39;s primary E-mail address is removed and sender&#39;s assumed E-mail address is used (susan01@storagemail.com). Receipt occurs with the primary E-mail address being maintained confidential “reply to” address is in the usual format (susan01@storagemail.com). 
   Presuming a non-subscriber (john) wishes to send an E-mail to a subscriber (susan). The E-mail is thus addressed to the intermediate server. Provision can be made for the substitution of the entire E-mail address. 
   Upon receipt at the intermediate server, an archive folder is opened or created with the sender&#39;s E-mail address and a copy of the E-mail archived therein. The message is resent from the intermediate server to the intended receiver. 
   Upon receipt at the intermediate server, the receiver&#39;s assumed E-mail address is removed and receiver&#39;s primary E-mail address is used in the usual format (susan02@realemail.com). “Reply to” address automatically changes to john02%university.edu@storagemail.com or john02@university.edu.stroagemail.com. Other substitutions can be made within the scope of the delimiter example outline above. 
   Upon an original message from a sender to the assumed E-mail address of a subscribing receiver, the message is receiver at the intermediate server. Presuming there are previous messages from the sender to the subscribing receiver, an archive folder of the addressee is opened with sender&#39;s E-mail address and copy maintained. The intermediate server strips the assumed E-mail address, restores the primary E-mail address of the receiver, and forwards the message. Subsequent E-mails between the parties are archived in the created folder and forwarded with an identical protocol. There results an E-mail service assuring confidentiality of the primary E-mail address and providing archiving by addresses for convenient review of messages. 
   The system allows for the forwarding of past or pre-subscription E-mails. The forwarded E-mails are archived and directly accessed by the system and treated conventionally as set forth immediately above. 
   The protocol also allows the subscriber to have multiple primary E-mail addresses, archiving E-mails according to primary E-mail addresses and routing incoming E-mail to one of multiple primary E-mail addresses.

   DETAILED DESCRIPTION OF THE INVENTION 
   Referring to  FIG. 1 , non-subscribing sender J sends E-mail E to subscribing receiver S S  through intermediate server I. Non-subscriber sender J has obtained the assumed E-mail address of subscribing receiver S S  from other sources, for example WebPages. Subscribing receiver S S  wants to receive non-subscribing sender J&#39;s E-mail; subscribing receiver S S  does not want sender J to know her real E-mail address. 
   The E-mail is from non-subscriber john02@university.edu to susan01@storagemail.com with “susan01” being the user identifier, @ being the user identifier sign, and storagemail.com being the domain name of the intermediate server. For the purposes of this specification, these individual components of E-mail addresses will not be given nomenclature hereafter. 
   The E-mail is addressed to the subscribing receiver S S  at intermediate server I. This E-mail is resent from intermediate server I with both the “to” and the “reply to” addresses changed. 
   First, the subscribing receiver S S  E-mail address is changed. It is changed from its assumed E-mail address to its primary E-mail address at server I. 
   Second, the possibility of a reply has to be anticipated. Should subscribing receiver S S  choose to reply, the “reply to” section of the E-mail should be capable of being resent to intermediate server I with coding enabling retransmission to non-subscribing sender John. The sender&#39;s user identifier sign @ is replaced with a delimiter—for example %—and a user identifier sign and the intermediate server domain name concatenated to the end of the non-subscribing sender J&#39;s address. Thus the “reply to” has the form (john02%university.edu@storagemail.com). This is achieved either manually or automatically by server I to message before it reaches the receiver. 
   Referring to  FIG. 2 , the case of subscribing sender S S  sending a E-mail to non-subscribing receiver J can be understood. Subscribing sender S S  sends codes in the message to non-subscribing receiver J in the format similar to the “reply to” format illustrated immediately above. This coding can be manual, software assisted, and/or automated by conventional programming. 
   Upon receipt at intermediate server I, the E-mail is resent. Two changes occur before resending is made. 
   First, the “To” portion of the message has the original address of non-subscribing receiver J restored by the replacement of the delimiter (e.g. %) with the user identifier sign @ and user identifier sign and the domain name of the intermediate server removed. The E-mail is capable of regular transmission to the non-subscribing receiver J. 
   Second, subscribing sender&#39;s primary E-mail address is removed and an assumed E-mail address is used therefor. Thus, non-subscribing receiver J will only see the sender&#39;s identity as “susan01@storagemail.com”, the assumed E-mail address masking the primary E-mail address. 
   Reply occurs in the manner illustrated with respect to  FIG. 1 . 
     FIGS. 3 and 4  illustrate the folder by party aspect of this invention. When a subscriber J S  receives or sends an E-mail to any contact, conditional branch B occurs during retransmission of the E-mail interior of intermediate server I. Specifically, and for E-mails related to the same contact, the folders F is maintained. The folder contains—chronologically or other preferred orders—the correspondences to and from the same correspondent. Where a message is sent and or received from such a contact for the first time, a folder F is created. Thereafter, subsequent E-mails for the same contact are stored in that folder. All these are automatically archived. 
   Access to the folder can be easily understood. The reader will understand that the disclosed E-mail protocol set forth above does not require site logon. However, one access to folders by a subscriber is desired, logon is required. Thereafter, access to the folders compiled remotely by the intermediate server I can occur. 
   Finally, and with respect to  FIG. 5 , the system allows for the forwarding of past or pre-subscription E-mails. The forwarded E-mails are archived and directly accessed by the system and treated conventionally as set forth in  FIGS. 3 and 4 . 
     FIGS. 6 and 7  illustrate the use of this protocol for a subscriber having multiple primary E-mail addresses. System subscriber creates a folder and record every time he sends a E-mail to a new receiver from one of his primary E-mail addresses. The further correspondences with the same address will be saved in the same folder and incoming E-mail forwarded to that specific primary E-mail address of subscriber&#39;s. Simply stated, each primary E-mail address is treated as a discrete subscriber with messages being encoded with “To”, “Reply to”, and “Reply” information as previously set forth with respect to  FIGS. 1 and 2 . Further, individual folder F is created and thereafter filled with chronologically order or other preferred orders messages as set forth in  FIGS. 3 and 4 .
