Abstract

The invention is suitable for the computer network field, which provides a method, a device and a piece of equipment for filtering e-mails. The method comprises the steps as follows: the address messages of a sender and a receiver are acquired; IP addresses are filtered according to the IP address in the address message of the sender; when the IP address of the mail fails to pass the IP filtration, a white list corresponding to the address message of the receiver is enquired according to the mail address in the address message of the sender and a white list check is then conducted on the mail. The invention carries out the IP address filtration after the sender establishes an IP connection, and performs the white list recheck on the mail which fails to pass the IP address filtration, thus preventing the mail in the user white list from being intercepted mistakenly without influencing the regular communications while processing junk e-mails.

Description

technical field [0001] The invention belongs to the field of computer networks, in particular to an e-mail filtering method, device and equipment. Background technique [0002] With the rapid development of computer network technology, e-mail, as one of the most commonly used network applications, has become an important tool for network communication. However, a large amount of junk mails such as commercial advertisements and viruses generated thereupon bring great inconvenience to users' communication. Spam not only pollutes the network environment, occupies a large amount of transmission, storage and computing resources, affects the normal operation of the network, but also brings many security problems to users. [0003] Filter is a commonly used anti-spam technology, such as anti-spam plug-ins on mail servers, anti-spam gateways, anti-spam functions on clients, etc. , including keyword filtering, black and white lists, hash (Hash) technology, etc. [0004] In the pri...
