Description
Technical Field
The invention relates to the technical field of mail service, in particular to a method and a device for automatically adjusting a mail delivery strategy and a storage medium.
Background
Mail is delivered from a sending server to a receiving server and is transmitted by a Simple Mail Transfer Protocol (SMTP). Thus, the actual process of mail delivery is that of two SMTP servers communicating. The mail is delivered to a receiving server from a sending server, wherein the most critical link is the process that an SMTP server at a sending end is connected with an SMTP server at a receiving end, and the mail can be basically ensured to be normally delivered to an inbox of a receiver only by ensuring the smooth communication of the two servers.
Generally, to ensure the normal and stable operation of the SMTP server, the SMTP server intercepts external illegal connection requests through many technical means (for example, a high-frequency request in a short time may cause a large amount of resources of the SMTP server to be occupied, and cannot provide normal services to the outside), and the frequency resetting intervals may be different according to different factors such as resources owned by the mail server itself and a processing manner, and the frequency resetting intervals may be different for each domain name.
The existing method for dynamically adjusting the mail delivery strategy is to erect a proxy server between a sending client and a sending server, send a mail to the proxy server through a hypertext transfer protocol (HTTP), and directly refuse to send the mail for users or mails which do not meet a threshold or a rule.
The existing method for dynamically adjusting the mail delivery strategy has the following problems:
the rejection mode is too strong and is easy to intercept some normal business letters by mistake, thereby reducing the success rate of mail delivery and further causing inconvenience in mail communication.
