Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0024] A method of replacing the sending mail system cluster in this embodiment includes a terminal 1, DNS2, mail server 3 and MX record 4, the MX record 4 points to the mail server 3, and the DNS2 resolves the mail according to the polling method The above MX record 4;

[0025] Including the process of mail system cluster sending mail:

[0026] Step A: The terminal 1 initiates a request to send an email;

[0027] Step B: the terminal 1 requests the MX record 4 from the DNS2 through the address suffix of the addressee; if the MX record 4 exists, locate the mail server 3 pointed to by the MX record 4;

[0028] Step C: establish multiple DNS2 records and MX records 4 through the DNS2, and the DNS2 resolves multiple IP addresses;

[0029] Step D: using the virtual subnet card through the mail server...

Abstract

The invention relates to a method for replacing a sent mail system cluster. A terminal, a DNS, a mail server and MX records are included; a process of sending a mail by a mail system cluster is included; the process comprises the steps that: A, the terminal initiates a request for sending a mail; B, the terminal requests the DNS for the MX records through the address suffix of an addressee; and, if the MX records exist, the mail server appointed by the MX records is located; C, multiple items of DNS records and MX records are established through the DNS; and the DNS analyzes out multiple IP addresses; D, the mail server uses a virtual sub-network card, so that the analyzed multiple IP addresses are configured on the mail server; E, the DNS analyzes the MX records on the mail server in a polling manner; and F, strategy routing is added in a routing level; the IP addresses analyzed by the DNS in the polling manner are appointed as source IPs in a forced manner; and the mail is forwardedby the source IPs. By means of the method and system for replacing the sent mail system cluster disclosed by the invention, the problem that the mail cannot be sent to a target domain name due to thefact that the single IP mail sending frequency is too rapid and too much can be solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a system for replacing a mail sending system cluster. Background technique [0002] Email communication is the earliest communication tool between people on the Internet, and it is also an irreplaceable way for enterprises to communicate and handover. With the development of the Internet, e-mail security systems, e-mail virus protection, and anti-spam strategies have also resulted in the inaccessibility of some normal e-mails. [0003] Especially in the case of limiting the number of emails sent by a single IP to the target email domain name within 1 minute, some normal emails are directly discarded when they are sent to the target domain name. The reason for this is that the frequency of sending emails from a single IP at a certain time Too much too fast. Contents of the invention [0004] The purpose of the present invention is to propose a method and sys...
