Mail server system and mail distributing method

Abstract

The embodiment of the present invention discloses a mail server system, which includes: a mail distribution server, at least one mail delivery proxy server and at least one mail delivery proxy server. A method for mail distribution is also disclosed in the embodiment of the present invention, the method includes: A.MTA server sends a query request to NameServer according to the mail to be sent; B.NameServer selects the MDA server according to the query request, and sends the selected The address of the MDA server is returned to the MTA server; C.MTA server distributes the mail to the corresponding MDA server according to the address of the MDA server; D. The MDA server delivers the mail to the mail corresponding to the mail corresponding mailbox. Through the above-mentioned system and method, configuration file synchronization can be realized; all MDA servers in the mail server system can be utilized in a balanced manner, thereby improving the efficiency of the entire mail server system.

Description

technical field [0001] The invention relates to email transmission technology, in particular to a mail server system and a mail distribution method. Background technique [0002] Currently, the Simple Mail Transfer Protocol (SMTP) protocol used in the email transmission process is a store-and-forward protocol, which allows emails (hereinafter referred to as emails) to be sent to a final destination through a series of servers. FIG. 1 is a schematic diagram of an email transmission system using the SMTP protocol in the prior art. As shown in FIG. 1 , the mail transmission system using the SMTP protocol in the prior art includes: a mail user agent (MUA), a mail transfer agent (MTA) server, a mail delivery agent (MDA) server and a destination mailbox. Among them, MUA can provide an interface for users and is responsible for receiving, sending and managing user emails. Therefore, MUA can be regarded as a client software; the function of MTA server is to provide routing for rece...

AI Technical Summary

Problems solved by technology

However, when the number of mail delivery proxy servers in the system continues to increase, and the number of servers that need to deliver mail within the system also continues to increase, the synchronization of configuration files will become a big problem; moreover, when the mail delivery proxy server fails At present, the current method of manual synchronization of configuration files is not good enough in real-time, so once the configuration files are not synchronized or the configuration files are incomplete, it will lead to problems in the selection of mail delivery proxy servers

At the same time, the above method does not consider the status of the MDA server and the pros and cons of the network, but blindly selects the MDA server for mail distribution, which leads to unbalanced server usage and reduces server usage efficiency
