Distributed email system resistant to junk emails

Abstract

The invention discloses a distributed e-mail system which can resist junk e-mail. The system comprises at least two node units for users to apply and obtain an e-mail account number, inquire and obtain the network address of an e-mail receiver and send as well as receive an e-mail, at least a catalog service unit used for responding the user request of applying the e-mail account number, distributing the corresponding e-mail account number and transmitting the user e-mail account number and the network address which are adjacent with the node unit; the node unit is communication linked with the catalog service unit. The node unit comprises a unit for applying the e-mail account number, a unit for inquiring network address of other account number, a unit for sending e-mail, a unit for receiving e-mail and a storing unit. The invention has the advantages that the junk e-mail problem is solved completely and the forwarding among the original e-mail servers and the delay brought by the forwarding are saved.

Description

technical field [0001] The invention relates to computer network communication technology, in particular to a distributed mail system capable of resisting spam. Background technique [0002] The main form of the current Internet is C / S, that is, the form of server and client. Generally, the performance of the server is better, and the performance of the client is relatively poor. The server provides services, and the client obtains services. A typical application is the application of browser and WEB server. The WEB server provides various resources, such as text, pictures, music and so on. The user uses his own computer as the client to obtain related resources by accessing the server. The advantage of this mode is that the requirements for the user's client computer are relatively low, and it also simplifies the requirements for the user. The user only needs to be able to access the Internet. Obtain the required resources through WEB browsing. [0003] But the disadvant...

AI Technical Summary

Problems solved by technology

[0007] 2. Malicious users can forward a large amount of spam through those public or vulnerable mail servers, and because they often go through multiple jumps, it is often difficult to trace the final source

[0008] 3. Even if the user makes a judgment on the spam and deletes it locally, because it has been transmitted to the local mail server, the local mail server needs a certain space to save the spam; and the spam has already reached the local Mail server, already wasting a lot of bandwidth

[0009] 4. The definition of spam varies from person to person. The same email is spam for one user, but it may be the information needed for another user

Although the technical means are optimized and continuously learned according to the user's characteristics, there will still be false positives, so in the end, the user needs to make manual judgments

The above two methods are basically passive defense methods. After arriving locally, they simply delete spam emails, and there is no effective defense method against subsequent similar spam emails.
