Description

Mail delivery system, method, electronic device, and storage medium

Technical Field

The present invention relates to the field of electronic mail technology, and in particular, to a mail delivery system, a mail delivery method, an electronic device, a program product, and a storage medium.

Background

In the internet environment, email is the most formal communication channel between businesses and enterprises, and between businesses and clients. With the increasing market demand, common email delivery products are increasingly unable to meet the needs of various industries. The reasons for the present situation include server resource shortage, high cost and long period of enterprise development and maintenance, and the like.

In order to ensure the running stability of the system of the large mail service operator, a certain threshold value is set for the receiving flow, the connection number, the upper limit of the number of addressees and the like of mails in a server, the mails can be smoothly delivered to a user mailbox only when the mail is delivered within the set threshold value range, and if the threshold value is suddenly reduced by the operator, the delivery system of a client does not timely take corresponding measures, delivery can fail, even delivery IP can be pulled into an abnormal list, and the use of the mailbox is influenced for a long time.

Mail delivery systems use multiple different domain names to signal, often viewed by mail service operators as spam or directly intercepted outside. Therefore, the problems that the success rate of batch delivery tasks is low, the delivery IP or the domain name is frequently listed in an abnormal list by a mail service operator and the like are caused. In severe cases, these product problems can even hinder business development and economic benefits of the enterprise.

Detailed Description

Further advantages and effects of the present invention will become apparent to those skilled in the art from the disclosure of the present specification, by describing the embodiments of the present invention with specific examples. While the description of the invention will be described in connection with the preferred embodiments, it is not intended to limit the inventive features to the implementation. Rather, the purpose of the invention described in connection with the embodiments is to cover other alternatives or modifications, which may be extended by the claims based on the invention. The following description contains many specific details for the purpose of providing a thorough understanding of the present invention. The invention may be practiced without these specific details. Furthermore, some specific details are omitted from the description in order to avoid obscuring the invention. It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.

It should be noted that in this specification, like reference numerals and letters refer to like items in the following figures, and thus once an item is defined in one figure, it need not be further defined and explained in the following figures, defaults to the same definition.

It should be further stated that the method and the process are numbered for convenience of reference, but are not limited to the sequence, and the sequence of the steps is the same as that of the text.

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The data acquisition, storage, use, processing and the like in the technical scheme meet the relevant regulations of national laws and regulations.

The existing mail delivery implementation schemes are mainly two, namely, an application is provided for a site providing an email service, an authorization code of a smtp mail server of the site is obtained by registering a mailbox account on the site, and then the sending of the mail is realized by logging in the smtp mail server of the account and using a smtp communication protocol. However, in this usage scenario, the suffix (domain name) of the mail is a site providing the email service, which does not meet the requirement that many companies want the suffix to be the company name.

And secondly, a mail delivery system is built by a company with a demand to carry out batch delivery. However, this method has a great disadvantage in terms of time and cost, such as:

1. the labor cost for developing and operating a mail server is too high;

2. the purchase cost of software and hardware is high;

3. a mail server only has one domain name, can not use a plurality of domain names to deliver mails, and when a plurality of domain names are used, the delivery success rate is low, and the IP is easily pulled into an abnormal list by a site;

4. when the mass mails are delivered, the delivery efficiency is low, and the mails with high real-time requirements cannot be timely sent to the client mail end, so that the client experience is poor.

The present application thus proposes a mail delivery system based on SaaS (Software as a Service, just software as a service). The software and hardware cost of the mail delivery system developed by enterprises and the labor cost of development and operation are reduced, the development period is shortened, and the enterprises can obtain efficient, high-success-rate and reliable mail delivery service.

Fig. 1 is an application scenario diagram of a mail delivery method according to some embodiments of the present invention. As described above, in order to deliver an email, a site providing an email service is required, and in fig. 1, the server 20 is a site that can provide an email delivery service. The site may provide email services directly to individual users. In order to provide targeted email services to corporate type customers, i.e., customers who need to display specified domain names, a software system for enabling mail delivery, such as SaaS mail delivery system 10, may be provided based on server 20. The SaaS mail delivery system 10 is interposed between the server 20 and the tenants 30a, 30b, 30c, the tenants 30a, 30b, 30c are directly facing the email service provided by the SaaS mail delivery system 10, and the server 20 is not directly providing services to the mail sender, but provides support for hardware resources for implementing the email service. The tenants 30a, 30b, 30c can purchase services and corresponding security certificates from the SaaS mail delivery system 10, and the SaaS mail delivery system 10 configures domain names and egress IPs (IPs for delivering mail) for the tenants 30a, 30b, 30c, and can perform operations such as mail delivery, urgent, and filtering according to rights and priorities purchased by the tenants 30a, 30b, 30c, and rights configured by end users within the tenants 30a, 30b, 30 c.

The mail delivery work can be realized by using the SaaS platform based on the same server 20 to realize the site of the email service of a plurality of software layers, and a special email service is provided for a plurality of enterprises and communities.

Fig. 2 is a block diagram of a mail delivery system according to some embodiments of the present invention, including: tenant unit 11, pre-management unit 12 and delivery unit 13.

The tenant unit 11 is used for managing basic information of tenants. After the tenant purchases the service, the tenant unit 11 assigns thereto a user name, a password (authorization code) and a delivery server (e.g., server 20) IP and a port number of the SaaS mail delivery system 10, and the tenants 30a, 30b, 30c establish a connection with the SaaS mail delivery system 10 based on the smtp protocol and use the service of sending mail.

The pre-management unit 12 is used to configure delivery services prior to delivering mail. Specifically, the front-end management unit 12 may perform various management tasks such as tenant management, delivery task management, abnormal list user management, statistics report management, delivery domain name and IP management, and parameter configuration management.

Preferably, the pre-management unit 12 may include a domain name and IP management subunit. The domain name and IP management subunit is used for carrying out correspondence matching on the delivery domain name of the tenant and the IP resource of the system. Specifically, the tenant unit may configure a respective delivery domain name for each tenant, and the mail delivery system may provide multiple egress IPs to the tenant to configure spf resolution of the domain name. Wherein, part of the exit IP is shared, and part of the exit IP is exclusive. The shared export IP can be shared with other tenants, and the delivery success rate and the resource utilization rate can be improved. The shared export IP is a high-quality IP address with higher scores in each large mail operator, and is used for improving the success rate of applying a normal list in the operators by a sender account and improving the delivery success rate. The number of egress IPs of the general shared type is larger than the number of egress IPs of the independent type. The independent export IP mainly solves the problem that part of mail operators require spf analysis of domain names to be mutually bound.

The pre-management unit 12 may also deliver a task management subunit. When the number of mails in the current time period is too large, the sending sequence queuing of the multi-tenant mails is carried out through a tenant queuing algorithm, so that important and urgent mails are delivered preferentially. For example, when the delivery number of mail exceeds a first threshold (e.g., 3000 pieces/minute) per unit time, the delivery task management subunit may calculate the priority of each mail and sequentially send the mail according to the priority. The priority may be calculated comprehensively according to scores of tenant, sender scenario, sender, mail size, and site failure rate. Wherein, the positive score of tenant, the scene of sending, the sender and the mail size, the failure rate of the site is a negative score.

Specifically, the priority calculation formula is as follows:

p (a, B, C, D, E) =a (a) +b (B) +c (C) +d (D) -E (E) formula (1)

Wherein a (a) =w1×a, score for tenant; b (B) =w2×b, scoring the delivery scenario; c (C) =w3×c, scoring the sender; d (D) =w4/D, mail size score; e (E) =w5×e, which is a station failure rate score.

In the tenant score, W1 is a high-quality tenant weight weighting factor, and is defined by the SaaS mail delivery system 10; a is a value factor rated by the good tenant, the value of a is rated by the SaaS mail delivery system 10, and a larger value of a (a) represents a higher score.

In the delivery scene score, W2 is a delivery scene weighting factor, which is defined by the SaaS mail delivery system 10; b is the higher the real-time requirement of the scene, the larger the value factor (such as higher priority of mail sending verification code and lower push score of marketing activity), the larger the value of B is rated by the SaaS mail delivery system 10, and the higher the value of B (B) is, the higher the representative score is.

In the sender scoring, W3 is a sender grade weighting factor and is defined by a platform; c is a value factor of the sender level, the value of C is given by the tenant, and the larger the value of C (C) is, the higher the score is represented.

The mail size scores are medium, and W4 is a mail file size weighting factor; d is a value factor of the mail file size, the value of D is determined by the mail file size, and the higher the score is represented by D (D).

In the site failure rate scoring, W5 is a site delivery failure rate weighting factor; e is a factor of the delivery failure rate of a site, and e is a value of the delivery failure rate of the site on the same day (e.g., qq mailbox, 163 mailbox serving as the server 20). A larger value of E (E) represents a lower score.

Further, in order to avoid that a weighting item is too high to affect the value of the priority by other weighting items, a relationship between multiple weighting factors may be defined, for example, a sum of the weighting factors may be defined as a predetermined value K, that is, w1+w2+w3+w4+w5=k. After defining K, the maximum difference between the weighting factors is K, and the weight ratio of the weighting factors can be limited to a certain extent.

The delivery unit 13 delivers the mail of the tenant to the target mailbox according to a predetermined rule based on the parameters configured by the pre-management unit 12. Based on existing server technology, mail delivery services can be implemented using a multi-server cluster. The cluster server can enable the mail delivery system to have super-strong stability, not only can balance the work load of each server, but also can avoid single-point faults of the system, and is convenient for expanding the delivery server.

In addition, the multiple servers bring more IP resources, and the delivery unit 13 can adopt a mechanism of using the shared IP and the independent IP simultaneously, namely a delivery processing mechanism of the shared IP and the independent IP to deliver the mail, thereby improving the success rate of mail delivery. Because if single IP delivery (e.g., standalone IP) is employed, it may be severely wasted due to the bandwidth limitations of the single IP delivering the destination server. Assuming that a total of 100 shared ip+independent IP that can be used by one tenant, the delivery unit 13 may use a polling method to sequentially use the 100 IP to attempt to send the mail to the target mailbox until the mail is sent successfully. In poor environment, it is possible to poll one round and unable to send out mail, and then poll (i.e. retry mechanism) can be repeated multiple times, so as to increase the success rate of delivery in a mode of multiple attempts.

More specifically, in an application scenario where multiple tenants share a set of shared IPs, in general, multiple tenants (corresponding to multiple domain names) share one IP, that is, mail of multiple domain names is sent through the same IP. When a first tenant in a group of tenants sharing the first IP is identified as a low reputation user, even pulled into an abnormal list, the first IP will be limited or blocked, and then all tenants sharing the first IP, including the first tenant, cannot continue sending mail normally through the first IP. At this time, each of a group of tenants using the first IP may be temporarily assigned an independent IP, respectively, so that the group of tenants can send mail through the independent IP. After the independent IP is used for sending the mails, the behaviors of the mails sent by the tenants are in one-to-one correspondence with the IP addresses, so that the problem of total blocking caused by the bad behaviors of one tenant of a plurality of tenants sharing the same IP is solved.

For the blocked first IP, the delivery unit 13 may attempt to send mail through the first IP at regular or irregular intervals to monitor the transmission success rate of the first IP, and when the transmission success rate is restored to above the success threshold, the first IP may be considered to be unblocked, so that normal use of the first IP may be restored.

In combination with the foregoing polling method, when the delivery success rate of the first IP is low, it may: first, mail is sent for a group of tenants using the first IP using other shared IPs (specifically, a single tenant may try different shared IPs, respectively), and when all shared IPs cannot successfully send mail, an independent IP may be temporarily assigned for a group of tenants using the first IP (or a tenant of the group of tenants that has not successfully sent mail by using other shared IPs), thereby sending mail through the independent IP. Meanwhile, the delivery unit 13 monitors the first IP, and when the delivery success rate of the first IP is restored to a predetermined success threshold, a group of tenants who originally use the first IP may be reset to commonly use the first IP.

In other embodiments, the mechanism by which the shared IP and the independent IP are used simultaneously may also select the IP based on the number of targeted sites delivered. For example, when the number of target sites delivered is less than or equal to the site threshold M, all shared IPs and independent IPs are used for polling delivery; when the number of the target sites delivered is greater than the site threshold M, the delivery success rates of all the shared IPs and the independent IPs for each target site are calculated respectively, for sites with high success rates, only the shared IPs can be selected for delivering mails, for sites with low success rates, only the independent IPs can be selected for delivering mails, for example, for a first target site, if the delivery success rate of the shared IPs is greater than the delivery success rate of the independent IPs, the shared IPs are used for delivering mails, and otherwise, the independent IPs are used for delivering mails.

The threshold M of the station may be determined by the number of deliveries at the time of peak delivery success rate of the station in the past period of time. For example, let site Z have n delivery success rate peaks for shared IP in the past month: p (IPa 1, Z), P (IPa 2, Z) … P (IPan, Z), the n delivery success rate peaks of independent IP are: p (IPb 1, Z), P (IPb 2, Z) … P (IPbn, Z). Respectively calculating average values to obtain:

Pa=（P(IPa1,Z)+P(IPa2,Z)+…+P(IPan,Z)）/n

Pb=（P(IPb1,Z)+P(IPb2,Z)+…+P(IPbn,Z)）/n

if Pa is greater than or equal to Pb, the shared IP is used for sending the mail, and if Pa is less than Pb, the independent IP is used for sending the mail.

In still other embodiments, whether a shared IP or an independent IP, when the delivery success rate of a certain IP is too low, the IP may be stopped from being used, and in turn, an IP with a higher delivery success rate may be used to deliver mail. For example, when the delivery success rate of the first IP is smaller than the first delivery threshold Pmin, the use of the first IP is suspended, and the delivery task of the first IP is delivered to the second IP with the delivery success rate larger than the second delivery threshold Pmax. The first delivery threshold Pmin and the second delivery threshold Pmax may be both fixed preset values, or the second delivery threshold Pmax may be the maximum value of the current delivery success rate. If the delivery success rate of all the IPs is smaller than the first delivery threshold Pmin, the situation needs to be fed back to the mail delivery system.

In addition, when the delivery success rate of a sender under a certain tenant name is low, the SaaS mail delivery system can analyze various mail return reasons returned by the target server and feed the mail back to the tenant, and the mail contents are required to be modified so as not to influence the domain name reputation, and the use of the shared IP is stopped.

In the SaaS mail delivery system, the tenant can purchase service and configure the sending domain name and the outlet IP of the tenant module, so that a self-built mail server can be avoided, funds for purchasing hardware resources can be saved, and technical cost of post-maintaining a mail system and the like can be saved. The SaaS mail delivery system calculates the delivery sequence of the large-batch mails of the tenants through a special tenant queuing algorithm in the front-end management unit, preferentially provides service for high-quality users and emergency mails, and improves the user experience. The delivery success rate is improved by using a delivery processing mechanism of the shared IP and the independent IP, so that each tenant can use an independent domain name, the reputation of the low domain name due to IP cross infection during delivery of the domain name of the shared IP can be reduced, and the resource utilization rate can be improved.
