Abstract

A method is provided for preventing the delivery of unwanted electronic mail messages to a destination client. An original electronic mail message is first received from a source client at a destination server. Next, a reply electronic mail message is sent from the destination server to the source client requesting the source client to complete a registration process to register the source client's electronic mail address with the destination server. The original electronic mail message is only sent from the destination server to the destination client when the source client properly registers the source client's electronic mail address.

Description

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to methods used to reduce the amount of unwanted electronic mail (e-mail) received by a user of an e-mail service.
2. Related Art
The problem of unwanted, i.e. “junk,” e-mail is well known and has received considerable attention. However, some background is thought to be of help in understanding the problem and the solutions that have been previously used or proposed, as well as the basic e-mail process. Referring to FIG. 1, there is shown the conventional process of sending e-mail messages from a source client 10 to a destination client 40. After the source client 10 composes an e-mail message, the message is sent from the source client 10 to a source simple mail transfer protocol (SMTP) server 20. The source SMTP server 20 sends the e-mail message to a destination SMTP server 30, which then sends the e-mail message to the destination client 40. A major drawback in the conventional process is the ever increasing amount of junk e-mail messages received by the destination clients 40. Such junk e-mail messages include advertisements for numerous goods and services. Users of e-mail systems have been spending an increasing amount of time separating their regular e-mail messages from unwanted e-mail messages.
Attempts have been made to reduce the number of junk e-mail messages received by the destination clients. Some methods require the source client to add descriptive information to the e-mail message so that the destination SMTP server can prevent undesired e-mail messages from being sent to the destination client. These methods are basically ineffective because the senders of junk e-mail messages will not add the descriptive information which will allow destination clients to block the junk e-mail messages.
Filter-out methods have also been developed. With such filter-out methods, a database of known sources (source clients) of junk e-mail messages is compiled. The destination SMTP server compares the source client's e-mail address to the e-mail addresses in the database and does not sent undesired e-mail messages to the destination client. These methods have also proven to be ineffective because the development of robotic delivery programs. These robotic delivery programs sent out thousands of junk e-mail messages and create nonexistent source client e-mail addresses. Thus, when one source client e-mail address is blocked, a new address is created. As a consequence, the database of known sources of junk e-mail messages can not keep up with changing e-mail addresses created by the robotic delivery programs.
SUMMARY OF THE INVENTION
According to the invention, a method for preventing delivery of unwanted electronic mail is provided which overcomes the problems of prior art methods discussed above. The method of the invention thwarts conventional robotic delivery programs and, in preferred implementations, includes features which will counteract the anticipated use of more sophisticated robotic delivery systems.
In accordance with a first preferred embodiment of the invention, a method for preventing the delivery of unwanted electronic mail messages to a destination client is provided which comprises the steps of: receiving an original electronic mail message from a source client at a destination server; sending a reply electronic mail message from the destination server to the source client requesting that the source client complete a registration process; monitoring the response of the source client to the request to complete a registration process to determine whether the source client properly responds to the request; and sending the original electronic mail message from the destination server to the destination client only if the source client properly responds to the request to complete a registration process.
In another preferred embodiment, a method for preventing the delivery of unwanted electronic mail messages to a destination client is provided which comprises the steps of: receiving an original electronic mail message addressed to a destination client from a source client having an electronic mail address at a destination server; comparing the electronic mail address of the source client to an accept list of electronic mail addresses; sending the original electronic mail message to the destination client when the electronic mail address of the source client is on the accept list; sending a reply electronic mail message from the destination server to the source client requesting that the source client complete a registration process when the electronic mail address of the source client is not on the accept list; monitoring the response of the source client to the request to complete a registration process to determine whether the source client properly responds to the request; and sending the original electronic mail message from the destination server to the destination client only if the source client properly responds to the request to complete a registration process.
In accordance with yet another preferred embodiment of the invention, a method for preventing the delivery of unwanted electronic mail messages to a destination client is provided which comprises the steps of: receiving an original electronic mail message addressed to a destination client from a source client having an electronic mail address at a destination server; comparing the electronic mail address of the source client to an accept list of electronic mail addresses; sending the original electronic mail message to the destination client when the electronic mail address of the source client is on the accept list; comparing the electronic mail address of the source client to a reject list of electronic mail addresses when the electronic address of the source client is not on the accept list; deleting the original message when the electronic mail address of the source client is on the reject list; sending a reply electronic mail message from the destination server to the source client requesting that the source client complete a registration process when the electronic mail address of the source client is not on the reject list; monitoring the response of the source client to the request to complete a registration process to determine whether the source client properly responses to the request; and sending the original electronic mail message from the destination server to the destination client only if the source client properly responds to the request to complete a registration process.
Preferred implementations for the registration process include: answering a question included in the reply electronic mail message; completing a form at an Internet address; and following instructions via a telephone system.
Other features and advantages of the invention will be set forth in, or apparent from, the following detailed description of the preferred embodiments of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1, which was discussed above, is a schematic block diagram of a conventional e-mail system.
FIG. 2 is a flow chart illustrating a method of blocking junk e-mail messages in accordance with a preferred embodiment of the invention.
 DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 2, there are shown the basic steps in a method of reducing the amount of junk e-mail received by a user of an e-mail service in accordance with a preferred embodiment of the invention. In a first step 60, a source client composes an e-mail message and the message is sent to the source SMTP server. Then, in step 70, the source SMTP server sends the e-mail message to the destination SMTP server. In step 80, the destination SMTP server compares the source client's e-mail address to an accept list. The accept list contains the e-mail addresses of source clients from which the destination client wishes to receive e-mail messages. In one implementation, the accept list is automatically updated to include the e-mail addresses of clients to which the destination client has sent e-mail messages. In all implementations, if the source client's e-mail address is on the accept list, the destination SMTP server sends the e-mail message to the destination client, as indicated in step 90. In step 100, if the source client's e-mail address is not on the accept list, the destination SMTP server determines if the source client's e-mail address is on a reject list. The reject list may contain e-mail addresses of known sources of junk e-mail and any e-mail address from which the destination client wishes not to accept e-mail. If the source client's e-mail address is on the reject list, the e-mail message is deleted by the destination SMTP server, as indicated in step 110. In an alternative embodiment, the e-mail message is held in a memory which is accessible by the destination client when the source client's e-mail address is on the reject list.
If the source client is not on the reject list, the destination SMTP server holds the e-mail message in memory and requests that the source client proceed with a registration process, as indicated in step 120. There are many different ways in which the source client can register its e-mail address. In one advantageous implementation, the destination SMTP server sends a reply message to the source client and requests that the source client send back a reply message. When the destination SMTP server receives the reply message, the original e-mail message is “filtered-in” and released to the destination client. However, if the original message is junk e-mail produced by a robotic delivery program, the destination SMTP server will never receive a response to its reply message because the source client e-mail address does not exist.
As robotic delivery programs become more sophisticated, it will become necessary to make the registration process more complex. For example, the destination SMTP server can send a reply message to the source client with instructions or a question that only a human can follow or answer, respectively. The registration process is successfully completed when the source client responds correctly. In a preferred implementation, each destination client is allowed to compose their own question and answer or instructions, in order to maximize the amount of effort required by a source of junk e-mail to send messages to multiple destination clients. In general, it will be cost prohibitive for the source of junk e-mail messages to go through and response to each destination SMTP server reply message. In other embodiments, the registration process is completed by filling out an Internet web page form or by following instructions via a telephone system. Although these embodiments have particular benefit, those skilled in the art will appreciate that there are many different ways in which the registration process can be performed. One advantage of including such a registration process is that it requires the source client to make an effort to filter-in a desired message, instead of requiring the destination client to filter-out undesired messages.
In step 130, the destination SMTP server determines whether the source client properly registered its e-mail address within a predetermined time period. The length of the predetermined time period may be selected either by the destination client or the destination SMTP server. If the e-mail address is properly registered, the original e-mail message is sent to the destination client and the source client's e-mail address is added to the accept list, as indicated in step 150. At any time, the destination client can add e-mail addresses and remove e-mail addresses from the accept and reject lists. Therefore, if the source client does properly register its e-mail address and the destination client wishes to not receive any more e-mail messages from that source client, the destination client can remove that entry from the accept list and add it to the reject list.
In the illustrated embodiment, if the registration process is not successfully completed within the predetermined period of time, the destination SMTP server holds the original e-mail message in a memory, as indicated in step 140. The destination client may access the e-mail messages stored in the memory. The destination SMTP server may delete the e-mail messages from the memory when a preselected event occurs, i.e., when instructed to do so by the destination client, or when a predetermined time period has lapsed, or when the memory is full or when a predetermined number of e-mail messages has been exceeded. Either the destination SMTP server, or the destination client can determine the manner in which the e-mail messages will be deleted from the memory.
In another embodiment (not shown), the destination SMTP server automatically deletes the original e-mail message if the registration process is not completed within the predetermined period of time.
One of ordinary skill in the art will appreciate that the software necessary to carry out the present invention may operate either from the destination server or the destination client.
Although the invention has been described in detail with respect to preferred embodiments thereof, it will be apparent to those skilled in the art that variations and modifications can be effected in these embodiments without departing from the spirit and scope of the invention.
