Mail transmission method and equipment used for mail transmission

Abstract

The invention discloses a mail transmission method and equipment used for mail transmission. The method comprises the steps that connection request information of user equipment to a remote mail server is monitored and intercepted by a self-driven layer; connection of the user equipment, a local mail server and the remote mail server is established in turn according to the connection request information; the local mail server receives mail data information of the user equipment; the mail data information is analyzed and processed so as to acquire data to be transmitted; the local main server transmits the data to be transmitted to the remote main server; and connection of the local main server and the remote main server is disconnected. With application of the mail transmission method and the equipment used for mail transmission, the mail transmission method and the equipment used for mail transmission have advantages of being stable and reliable and easy to extend, and an unencrypted mail address can be specified without influencing user behaviors and security is high.

Description

technical field [0001] The invention relates to the field of computer network security, in particular to a mail transmission method and equipment used for mail transmission. Background technique [0002] With the advent of the information age, the rise of e-mail has increased the channels for information exchange. People can exchange various types of information at any time in different places. In some enterprises and units, employees can obtain a large amount of valuable information.

Some enterprises and units even set up their own mail servers to facilitate employees to send, modify and audit mail content. [0003] E-mail is a double-edged sword. While greatly improving our work efficiency and facilitating information exchange, it also creates the risk of information leakage. The number of leakage cases is increasing year by year. At present, in order to solve the security problem of l...

Problems solved by technology

At present, in order to solve the security problem of leaking secrets through e-mail, the following schemes are currently mainly used. Although they also play a certain role in protection, there are also large loopholes and deficiencies:

However, there are many types of mail clients. To support all clients, the implementation is cumbersome and not stable, and the hooks in the application layer are easy to be cleared by employees using security tools, so the security is not high.
