Email has become an important tool for office communication in all walks of life. The Mail System Software on the market is wide-ranging, there are commercial self-built mail server software, business-rented enterprise mail, open-source self-built mail server software, and free enterprise mail, and each type of brand is also very rich. How can enterprises choose the mail server suitable for the enterprise among so many products?

In this case, enterprises need to first understand themselves, understand the differences in various forms, and position their needs, including functional requirements, data security requirements, and price budgets; then, are you sure you want to create a self-built email system or rent an enterprise mailbox?

If you choose to build your own, is it a commercial purchase? Or open source? If you select enterprise mail, do you want to rent enterprise mail? Or is it free enterprise mail? The following describes four methods one by one.

I. self-built email system

If an enterprise chooses to build a self-built email system, it must have: servers, fixed IP addresses, and technical staff (part-time or dedicated-time maintenance servers). If an enterprise chooses to build a self-built email system, the data is stored on its own server, managed by internal personnel of the enterprise, the data is more secure and flexible (for example, the archiving service and backup mechanism can be enabled to retrieve historical data as audit or query at any time)

1. Open-source self-built

Open-source self-built, that is, the selection of mail server software is open-source, select the advantages of open-source products: enterprises do not need to invest in software costs. However, an enterprise must be familiar with the technology. Disadvantages of open-source products: No manufacturer training, no after-sales service, completely dependent on the technical strength of the enterprise; and in the anti-spam and anti-virus aspects, open-source products are relatively weak, enterprises need to use their technologies to find third-party anti-spam software. Open-source companies do not provide overseas relay services. If there are overseas business exchanges, they also need to use overseas relay services provided by professional manufacturers; open-source products are relatively popular and have relatively simple functions, such as sending and receiving emails. Open-source products have relatively poor integration. Therefore, open-source self-built systems are suitable for enterprises that do not have overseas business dealings, enterprises that have high-level technical staff, are not particularly demanding on functions, and do not require integration.

1. Self-built business

Commercial self-built, that is, to buy mail server software provided by professional manufacturers, choose commercial self-built disadvantages: enterprises need to invest in software costs. Choose commercial self-built advantages: complete functions; professional manufacturers provide pre-sale, in-sales, and after-sales services; integrate or embed professional anti-spam software; provide professional overseas relay services; there are comprehensive secondary development interfaces for integration; one-time investment, and only a small amount of premium is required each year. Therefore, commercial self-built companies are suitable for technical staff (part-time or full-time) who have a software investment budget, high functional requirements, and the ability to maintain servers) high requirements on spam interception rate, overseas business exchanges, and integration of the mail system with other systems.

There are many brands of commercial self-built email server software. when selecting an email server, enterprises must pass tests to verify the functions and select the mail server software suitable for their own businesses.

2. enterprise mail

Enterprise mail is a hardware product provided by the operator and a server is set up. Enterprises only use some of the space to send and receive emails. enterprises do not need to maintain hardware and software, however, the data backup is unified by the carrier for a short time or even no backup data is provided. Therefore, the retention of historical data depends on the user's personal client.

1. Free enterprise email

Currently, most enterprise mailboxes on the market are free of charge, and the number of users is less than 200. Enterprises only need to apply for and create their own users. Free enterprise mail advantages: enterprises do not have to pay any fees, nor need technical staff to maintain. Disadvantages of free enterprise mail: no technical payment is available, and stability is affected. If you encounter problems such as bounce and no technical solution is provided, you can only resend or change the email address; data is stored on the carrier's server, and data security is not guaranteed. enterprise mail features are popular and can only be used for sending and receiving simple emails. The user space and attachment size are centrally configured by the carrier, and the enterprise has no permission to modify them; cannot be integrated with other systems; the number of enterprise users cannot exceed 200; no backup data is provided. Free enterprise mail is suitable for enterprises: enterprise users cannot exceed 200, do not have high requirements on mail system functions, do not have system integration requirements, do not pay attention to data security, and do not pay attention to historical data management.

2. Rent an enterprise mailbox

The Enterprise mailbox is used to rent the email server space created by the carrier. The advantage of renting an enterprise mailbox is that the enterprise does not require hardware costs or maintenance by technicians. Disadvantages of renting an enterprise mailbox: data is on the carrier's server, and data security is not guaranteed. enterprise mail features are popular and can only be used for sending and receiving simple emails. The user space and attachment size are centrally configured by the carrier, enterprises do not have the permission to modify; they cannot perform personalized development. They provide limited secondary development interfaces and poor system integration. The annual investment required is the same or increases year by year. In the long run, the cost is relatively high; the backup data period is relatively short (for example, within one month or three months ). Enterprises suitable for renting enterprise mailboxes are: each year, the mail system has a budget, does not have high requirements on the function of the mail system, does not have system integration requirements, does not pay attention to data security, and does not pay attention to historical data management.
