Problems solved by technology

[0002] The traditional mail gateway technology only has the functions of general mail sending and receiving and dumping, and its performance is low. With the increasing number of spam, there are many anti-spam gateway products on the market, which play a certain role in anti-spam function, but overall, they still have many deficiencies:
[0004] (2) Intelligent filtering of multi-feature spam: the intelligent filtering system relies on information filtering technology, but the existing intelligent identification and filtering system is not ideal, especially the improved algorithm for training is not reasonable
[0005] (3) The overall system efficiency of the anti-spam gateway: At present, the anti-spam gateway is facing a dilemma between accuracy and efficiency. If simple keyword matching rules are used, it is easy for spammers to take advantage of loopholes; Complex rules, too low efficiency, not practical
[0006] Among the currently commonly used anti-spam methods, various anti-spam models have their advantages and disadvantages. If they are integrated to achieve multi-layer filtering, the accuracy of filtering garbage will be improved due to complementarity, but the implementation Multi-layer filtration, due to the use of many filter modules, will not only reduce the efficiency due to mutual influence, but also reduce the stability of the system operation, and sometimes the entire system may collapse due to a problem in one link

Embodiment Construction

[0017] specific implementation plan

[0018] In this example, after the scheduling module EPS of each node of the gateway receives the mail from the mail domain, the master management process starts the EPS process, and the EPS process takes out the filtering rules from the rule database for filtering, and then the master management process starts other filtering in turn The module filters the mail, and the mail enters the mail backend system after filtering.

[0019] See the specific process figure 2 , the mail is transmitted through the Internet, and the mail service node scheduling module first mobilizes the smtpd module in the EPS process to perform frequency control filtering, RBL filtering, black and white list filtering, and invalid domain filtering after the mail service node scheduling module receives the mail. Request the anvil process, frequency control filtering can control the connection frequency of the mail sender when sending mail, if the connection frequency...

Abstract

A method for setting up multi-layer and anti-garbage gateway frame features that a multi-layer garbage filter module is arranged on the gateway node in the front of MTA of mail server and the gateway frame is running in the mode of Master manage progress to monitor the running of relative modules in memory and starting or stopping various garbage filter modules according their configuring parameters, so in creasing the filtering efficiency.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to a method for setting an anti-pull garbage gateway framework on the network. Background technique [0002] The traditional mail gateway technology only has the functions of general mail sending and receiving and dumping, and its performance is low. With the increasing number of spam, there are many anti-spam gateway products on the market, which play a certain role in anti-spam function, but overall, they still have many deficiencies: [0003] (1) Behavior feature recognition method: The current behavior feature recognition method is relatively simple, but in fact, the behavior of spam has many common features, and it is necessary to further mine the behavior of spam and propose a more effective recognition method. [0004] (2) Intelligent filtering of multi-feature spam: The intelligent filtering system relies on information filtering technology, but the existing ...
