[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
