Description

technical field [0001] The invention relates to electronic mail (E-mail) processing technology, in particular to an anti-spam processing device and method. Background technique [0002] At present, spam is rampant on the Internet, causing great troubles to many network users. In order to solve the above problems, network service providers are studying anti-spam methods in order to better filter out spam on the network. [0003] The method of existing anti-spam mainly contains following several: 1) filter spam based on the key character string of rule; 2) adopt statistical algorithm to classify and identify spam, such as Bayesian algorithm etc.; Intercepting spam; 4) Control methods such as flow limitation on sending behavior. The above anti-spam processing methods can be used alone or in combination, and are suitable for application on mail servers and / or mail processing devices at individual client terminals. FIG. 1 shows the structure of an existing mail processing devi...

AI Technical Summary

Problems solved by technology

[0010] For the language correlation method, spammers change the language and text character set of the email body, so that technologies such as Chinese word segmentation cannot effectively filter out spam

[0011] For traffic control methods, spammers slow down the frequency of sending spam, or control the number of emails sent by the same account, so that spam cannot be identified

[0012] It can be seen from the above description that almost all commonly used anti-spam technologies have been cracked by spammers, that is, the update frequency of anti-spam technology is far behind that of spam sending technology, which makes the network unable to provide satisfactory Anti-spam effect
