Electronic mail system

Abstract

The disclosed E-mail system comprises: a server, including a user proxy module with a Web Service container, a mail transmission proxy module, and a mail distribution proxy module; and a client. Wherein, the Web Service container comprises a main package sub-module, a mail transmission sub-module, a mail receiving sub-module, a mail decomposition sub-module, a user key management sub-module, an enciphering / deciphering sub-module, and some corresponding calling interfaces. This invention avoids repeated development, and has wide application, such as PC, palm PC, and mobile phone.

Description

technical field [0001] The present invention relates to electronic mail (Email) systems, especially mail user agent systems. Background technique [0002] With the increase of people's activities on the network, email services are becoming more and more important in people's daily life, and a large amount of sensitive information needs to be disseminated on the network. People's requirements for the convenience and security of email services are getting higher and higher. At the same time, more and more intelligent mobile terminal devices such as mobile phones, personal digital assistants (PDAs), and handheld computers (Pocket PCs) are gradually integrated into people's lives. Requirements are gradually emerging, so how to enable email users to send and receive emails in various fixed or mobile environments is of great significance. [0003] The email system is mainly composed of three main modules: a mail user agent (MUA, Mail User Agent) module, a mail transfer agent (MTA...

Problems solved by technology

[0010] Referring to Figure 2, traditional email services have both application-based clients (C / S) and Web browser-based (B / S) clients. Figure 2 shows the traditional way of integrating C / S and The B / S solution only uses the data layer as a shareable module, and the application logic layer is implemented separately, which will inevitably bring about the following problems: Poor reusability: only the data layer is shared, and the logic layer needs to be redesigned ; Poor reliability: Repeated module design can easily lead to inconsistency in business logic; Poor scalability: Unable to provide interfaces for third-party development clients

[0011] At the same time, we can also see that to implement the mail user agent module in the above-mentioned APP mode and the above-mentioned webpage mode, it is actually necessary to repeatedly implement the logical application layer, resulting in repeated code development and waste of computing resources.

[0012] There are also solutions that use DCOM or CORBA protocol to access the middleware that constitutes the business logic module to achieve the integration of multi-client mode. Although these solutions fully realize the idea of ​​module design, they make up for the poor reusability of simple superposition solutions. However, DCOM can only be used on the Windows platform, and CORBA is not suitable for use in a loosely coupled environment. Its binary-coded distributed system has poor scalability and difficult configuration.

[0013] Another method is to customize the interface scheme to achieve integration. The principle is to use the XML language to define a dedicated protocol to negotiate the communication between the client and the server. Although this method has strong flexibility, it lacks Specifications and standards, very difficult to implement

[0014] All in all, the above-mentioned various implementation methods and methods have the above-mentioned shortcomings such as the need to repeatedly implement the logic application layer, and it is difficult to minimize the workload of the mail provider.

Such an implementation mode cannot adapt to the multi-application requirements of e-mail services on the current many types of carriers and many types of operating platforms. Therefore, it is necessary to propose a solution to solve the above problems
