Description

Email sending system and method

The present invention relates to an email transmission system and method.

With the development of computer technology, e-mail has become the main network tool for people's communication. At present, some large e-mail service providers have multiple e-mail sending servers, but because there are too many users, they still can't meet the needs of users, resulting in uneven operation of e-mail sending servers. The user's mail can't be sent out, and some servers are in idle state, which causes waste of resources, and also greatly wastes the user's time and reduces work efficiency.

In view of the above, it is necessary to provide an e-mail transmission system and method having a distributed load balancing function.

The email sending system includes an email processing platform, a database server, and a plurality of email sending servers, and the database server includes: a database, the database server further includes: an acquiring module, configured to receive the electronic The mail processing platform acquires an email to be sent; a saving module is configured to save the obtained email to the database; and a sending module is configured to send a viewing request command to each email sending server, the viewing request command For selecting the number of emails to be sent in each email sending server; receiving module for receiving the number of emails to be sent by each email sending server; and selecting a module for selecting the electronic to be sent The email sending server having the least number of mails; the sending module is further configured to send an email to the selected email sending server, and the email sending server sends the email to the recipient; and The receiving module is further configured to receive a sent email result fed back by the email sending server .

The email sending method includes the following steps: the database server acquires an email to be sent from an email processing platform and saves the email to a database; and sends a viewing request command to the database server Each email sending server checks the number of emails to be sent in each email sending server; receives the number of emails to be sent back by each email sending server; selects the email with the least number of emails to be sent Sending a server; sending an email to the selected email sending server, the email sending server sending the email to the recipient; and receiving the sending email result fed back by the email sending server Notice.

Compared with the prior art, the email sending system and method can utilize the email sending server in a balanced manner, thereby improving the sending efficiency of the email.

As shown in FIG. 1, it is a hardware architecture diagram of a preferred embodiment of the email transmission system of the present invention. The system includes an email processing platform 1, a database server 2, and a plurality of email sending servers 3. The email processing platform 1 may be: a host, a WEB server, or the like for sending an email to the database server 2, the database server 2 comprising: a database 200. The database 200 may be a SQL Server (Structured Query Language) database, and the database 200 is used as an email collector for collecting email related information to be sent from the email processing platform 1 and storing the email. Relevant information, including the content of the email, the sender's email address and the recipient's email address. The database server 2 is configured to select and activate an email sending server 3 to send an email, and the email sending server 3 is configured to send an email and feed the email sending result back to the database server 2. The plurality of email sending servers 3 also respectively include a cache 300 for storing emails to be sent.

As shown in FIG. 2, it is a functional module diagram of the database server 2 in FIG. The database server 2 includes an acquisition module 10, a storage module 12, a transmission module 14, a receiving module 16, a selection module 18, and a determination module 20.

The obtaining module 10 is configured to obtain an email to be sent transmitted by the email processing platform 1, the email including the sender email address of the email, the email address of the recipient, the content of the email, and the like.

The save module 12 is used to save the email to the repository 200.

The sending module 14 is configured to send a viewing request command to the email sending server 3 for viewing the number of emails to be sent in the cache 300 of each email sending server 3.

The receiving module 16 is configured to receive the number of emails to be sent in the buffer 300 fed back by the email sending server 3, and if there is an email sending server 3 that does not return the number of emails in the cache 300, Indicates that the email sending server 3 has failed.

The selection module 18 is for selecting the email sending server 3 with the least number of emails in the cache.

The transmitting module 14 is configured to send an email to the selected email sending server 3, and the email sending server 3 transmits the email to the recipient.

The receiving module 16 is further configured to receive a sending email result notification fed back by the email sending server 3, where the sending notification includes: sending the email success notification or sending a failure notification.

The determining module 20 is configured to determine whether the received sending notification is a sending success notification.

The deleting module 22 is configured to delete the email information in the database 200 when the received email sending notification is an email sending success notification.

As shown in FIG. 3, it is a flowchart of the operation of the preferred embodiment of the electronic mail transmitting method of the present invention.

Step S30, first, the obtaining module 10 acquires an email to be sent transmitted by the email processing platform 1, the email including the sender email address of the email, the email address of the recipient, and the content of the email. Wait.

In step S32, the saving module 12 saves the email to the database 200.

In step S34, the sending module 14 sends a viewing request command to the email sending server 3, which is used to view the number of emails to be sent in the cache 300 of each email sending server 3.

In step S36, the receiving module 16 receives the number of emails to be sent in the buffer 300 fed back by the email sending server 3, and if there is an email sending server 3 that does not return the number of emails in the cache 300, It means that the email sending server 3 has failed.

In step S38, the selection module 18 selects the email sending server 3 with the least number of emails in the cache.

In step S40, the transmitting module 14 sends an email to the selected email sending server 3, and the email sending server 3 transmits the email to the recipient.

In step S42, the receiving module 16 receives the sending email result notification fed back by the email sending server 3, and the sending notification includes: sending the email success notification or the sending failure notification.

In step S44, the determination module 20 determines whether the received transmission notification is a transmission success notification.

In step S46, the sending module 14 deletes the email information in the database 200 if the email sending notification is a sending success notification.

In the above step S44, if the received transmission notification is a transmission failure notification, the process returns to step S34 to re-search for the idle email transmission server 3.

The above is only the preferred embodiment of the present invention, and has been used in a wide range of applications. Any other equivalent changes or modifications which are not departing from the spirit of the present invention should be included in the following claims. Inside.
