## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is directed to a method of and apparatus for communicating via a network of computers, namely an electronic mail system wherein outgoing and incoming mail is categorized for added user friendliness.
2. Description of Related Art
The Internet has expanded the communications ability of a typical client/server environment wherein networked clients could communicate with each other. With the advent of the Internet, a typical home personal computer (PC) can communicate with another PC around the world without having to pay long distance telephone charges. Electronic mail (or e-mail) can be used to send messages to anyone who is connected to the Internet or to a computer network that has a connection to the Internet such as an online service.
E-mail software enables the user to read their e-mail after the Internet delivers the e-mail to the user's mail box, compose new mail, and respond to their messages. When someone sends an e-mail message via the Internet, the e-mail message is sent to a mail server wherein the e-mail software on the client computer logs in to see whether the user has any e-mail. When the user wants to read the e-mail message, the software downloads the message to the user's client computer where the user can read it, file it delete it, or respond to it.
Since the volume of e-mail has increased dramatically over the last few years, it is not uncommon to find tens or hundreds of e-mail messages waiting for the client user's response. The difficulty encountered by users nowadays has to do with managing the volume of e-mail being sent and received. In addition to legitimate e-mail from family, friends and colleagues, there is also junk e-mail known as “spam.” It is time consuming and tedious to have to review every e-mail message before finding the one of importance. Thus, it would be desirable to have a method and apparatus for categorizing the e-mail as it is being sent so that it may be categorized as it is received.
The typical e-mail software enables the user to create electronic storage sites to categorize and store e-mail that has been received. However, this method of storing the e-mail must be performed “manually” by the user after the e-mail software has downloaded the individual message onto the user's client computer. Upon reading the e-mail message, the user may store the message in an electronic folder in a category of their choosing for later reference.
Bearing in mind the problems and deficiencies of the prior art, it is therefore an object of the present invention to provide a method and apparatus for categorizing e-mail messages as they are sent and received.
It is another object of the present invention to provide a method and apparatus for sending and receiving electronic mail wherein the e-mail messages are categorized for added user friendliness.
A further object of the invention is to provide an electronic mail software for categorizing e-mail as it is sent and received.
Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
In describing the preferred embodiment of the present invention, reference will be made herein to FIGS. 1–4 of the drawings in which like numerals refer to like features of the invention. Features of the invention are not necessarily shown to scale in the drawings.
The present invention is a method and apparatus for classifying electronic mail as it is sent from a client computer of a sender to the client computer of a receiver. The present invention provides a method and apparatus for identifying and categorizing the mail into different storage sites or electronic folders when the e-mail message is received by the receiver's client computer. The advantage for the receiver of the mail is that specific types of mail may be accessed quickly without having to search through all of the e-mail received.
FIG. 1 is a schematic representation of a computer system which may be used to practice the present invention. Client computers 10, 30 are linked via a network server 20 such that the client computers are capable of sending information to and from each computer. Server 20 makes information available to both client computers 10, 30 using a communication protocol sent over a communication channel such as the Internet or through a dial-up connection, e.g., ISDN line. Client computers 10, 30 and server 20 are capable of utilizing program storage devices embodying machine readable program source code which causes the computers to perform the method steps of the present invention. The program storage devices of the present invention may be devised, made and used as a component of a machine utilizing optics, magnetic properties and/or electronics to perform the method steps of the present invention. Program storage devices include, but are not limited to, magnetic diskettes, magnetic tapes, optical disks, Read Only Memory (ROM), floppy disks, semiconductor chips and the like. The process of the present invention may be utilized as a “plug-in” or incorporated into an e-mail software program.
FIG. 2 is a flow diagram illustrating the method steps as it occurs at the sender's client computer. Step 100 begins the process of placing a selected category within the header of the e-mail message. The sender of the e-mail message writes 101 a message that will be sent from client computer 10. Once the e-mail message is completed the sender determines whether or not to send the e-mail message 102. If the sender decides to send the message later or not to send the message at all the process is terminated 106 and exited 107. However, if the sender determines that the e-mail message should be sent, a category is placed in the header of the e-mail 103. The header contains information about the file such as the filename, file size and a category identifier in accordance with the present invention. The present invention embodied in a computer program product can read or view the e-mail message at the receiver's client computer wherein the category identifier in the header distinguishes what file category the message is and processes it accordingly. The mail is then placed in the proper electronic folders or storage sites corresponding to the category included in the e-mail header. The e-mail is sent to the indicated receiver 105 and the sender determines whether or not to exit the program 106.
The present invention provides a category table from which a category identifier is selected 104 and the selected category identifier would then be included in the e-mail header. The category table of the present invention is illustrated in FIG. 4. The category table has entries comprising of different designators used in classifying the e-mail messages. These designators may include but are not limited to personal mail, payments, business mail, advertisements, etc. The designators correspond to the electronic storage sites in which the e-mail messages are stored upon receipt. A default “general mail” category may be added when the sender of the e-mail message does not categorize the e-mail message. Preferably, the category table may be edited by the user to add personalized categories to the predetermined ones.
FIG. 3 is a flow diagram representing the method steps of the present invention as it occurs at the receiver's client computer 30. The process 200 starts when the receiver determines whether or not the mail shall be placed in different electronic folders corresponding to the category identifier included in the e-mail header 201. If the receiver elects not to receive categorized mail, in-coming electronic mail is put in a general folder 203 wherein the messages can be viewed 206. If the receiver elects to receive the mail in categories, the mail is downloaded from server 20 at step 202. The mail is placed in the electronic folders or storage sites corresponding to the category identifier imbedded in the header of the e-mail message 204. The receiver may then select one or more of the folders from the categories 205 to view the mail 206 within the selected electronic folder.
The present invention achieves the objects recited above. The method and apparatus disclosed categorizes e-mail messages as they are sent and received by including a category identifier in the header of the e-mail message. The present invention provides a plurality of electronic storage sites which correspond to the category identifiers. When the e-mail messages are downloaded by a receiver onto their client computer, the e-mail message is stored in an electronic storage site according to its category identifier. A category table is provided which comprises a plurality of designators for categorizing the e-mail messages. There is increased user efficiency and friendliness since a recipient of numerous e-mail messages will not have to search through each e-mail message when looking for a particular message. They can look directly in the electronic storage site in the desired e-mail category to which the e-mail message pertains.
While the present invention has been particularly described, in conjunction with a specific preferred embodiment, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. It is therefore contemplated that the appended claims will embrace any such alternatives, modifications and variations as falling within the true scope and spirit of the present invention.
