Problems solved by technology

[0005] In the process of implementing the present invention, the inventor found that in the prior art, during the time when the gateway device caches mail, it is necessary to send part of the mail data to the client to ensure that the connection between the server and the client does not time out, and because the sent part of the mail data is It has not passed the content detection, so the email data sent may already have viruses or spam data, so that the client receives virus-carrying email data or spam data, resulting in the failure of the function of the gateway device

Abstract

The embodiment of the invention provides a mail processing method, gateway equipment and a network system, wherein the mail processing method comprises the following steps that: mails sent to a client end by a server are intercepted; safety detection is carried out to the mails; before the safety detection is completed, keep-alive data is sent to the client end; and the keep-alive data comprises the data in the headers of the mails or safety data unrelated to the mails. The technical scheme provided by the embodiment of the invention can improve the network security while reducing the timeout phenomenon when the client end receives the mails.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a mail processing method, gateway equipment and a network system. Background technique [0002] With the rapid development of Internet technology, e-mail has become a fast and economical means of communication technology. However, while providing people with extremely convenient communication, e-mail has also become a channel for spreading spam, viruses, malicious programs or sensitive content. It is an important carrier and poses a serious threat to system security. Therefore, mail gateway devices with anti-spam functions and virus detection functions are widely used. [0003] During the application process, the gateway device intercepts the mail sent by the server, and determines whether the mail is spam and whether the mail carries a virus by detecting the content of the mail. Specifically, the gateway device first caches all data (including attachments) of the mail, r...
