MAIL TRANSMISSION METHOD, SERVER AND SYSTEM
FIG8 is a schematic structural diagram of another node server according to some embodiments of the present disclosure  FIG7 is a schematic structural diagram of a node server according to some embodiments of the present disclosure
Based on the similar technical concept, the embodiments of the present disclosure further provide another node server, where the node server is applied to a mail transmission system including a first node and a second node, where the first node is configured to receive mail data transmitted by a transmitting terminal, and the second node is configured to transmit the mail data to a receiving terminal. The node server is coupled to the second node, and may implement a mail transmission method provided by any of the foregoing embodiments. FIG8 is a schematic structural diagram of a node server according to some embodiments of the present disclosure. As shown in FIG8, the node server 800 includes: a processing unit 801 and a transceiving unit 802.  Based on the similar technical concept, the embodiments of the present disclosure further provide a node server, where the node server is applied to a mail transmission system including a first node and a second node, where the first node is configured to receive mail data transmitted by a transmitting terminal, and the second node is configured to transmit the mail data to a receiving terminal. The node server is coupled to the first node, and may implement a mail transmission method provided by any of the foregoing embodiments. FIG7 is a schematic structural diagram of a node server according to some embodiments of the present disclosure. As shown in FIG7, the node server 700 includes: a processing unit 701 and a transceiving unit 702.

['10. A node server for application in a mail transmission system including a first node and a second node, wherein the first node is configured to receive mail data transmitted by a transmitting terminal, the second node is configured to transmit the mail data to a receiving terminal, the node server is coupled to the first node, and the node server includes a processing unit and a transceiving unit, wherein: the processing unit is configured to perform a fragmentation process on the mail data to obtain a plurality of data fragments, and for each data fragment: determine, based on historically transmitted mail data, whether the data fragment is a data fragment that has been previously transmitted, when the data fragment is a data fragment that has not been previously transmitted, transmit, through the transceiving unit, the data fragment to the second node, and when the data fragment is a data fragment that has been previously transmitted, transmit, through the transceiving unit, a feature value of the data fragment to the second node, wherein the feature value is used to instruct the second node to acquire the data fragment.']
