First, you need to understand the domain name (domain), domain name server (DNS), A records, and basic concepts of MX records. Please click here to view them simple introduction; second, you need to check if the MX log of the company has already existed. Click here to view the simple check method; then, you can set your own domain name MX record. For the case where the MX record already exists, if the MX record already exists, and it has already been checked on a domain name server, the job you need to do is to contact your domain name service provider or the domain name server, to record the MX record Change as follows: Your domain name 86400 in mx 1 mx.sina.net The above modification is complete, log in to "Enterprise Mailbox Management System", click "Add New Domain Name" in the Domain Name Settings, and then add according to the system prompt Your own domain name. For the case where the MX record does not exist, you can figure out that your domain name is exactly domain name parsing in which domain server (DNS), there are two ways to check the application information you submitted when you register the domain name, Get the unit accepting the application, contacting the unit of acceptance, letting the other person's related personnel will help you check it; the other is in WinNT, Win2000, or various UNIX operating systems, by using NSLookup. Once you have found your domain name, please contact your domain service provider or the administrator of the server, let the other party add a MX record, the form of the record is as follows: Your domain name 86400 in mx 1 mx.sina.net After the above setting is complete, log in to the Enterprise Mail Management System, click "Add New Domain Name" in the Domain Name Settings, and then add your own domain name according to the prompt of the system. Domain, Domain, Domain Server (DNS), A Record, and MX Record Basic Concept: For any valid domain name, there should be an authoritative domain server (DNS) of this domain name, there is one or more of the domain name servers. For the resource record of this domain name. A resource record has a total of 5, which are domain names (Domain_Name), survival time (time_to_live), type (TYPE), Class (CLASS), and value. Where: Domain Name: It is the domain pointing to this record; the survival time: points out the stability of the record. Highly stable information is given a large value, such as 86 400 (one day in seconds), the changed information is given a smaller value, such as 60 (1 minute); Type: Indicates the type of record, where Important types are:
Types of

value
SOA Start Of Authority The parameter A of this area A host IP address 32 Bit integer MX mail exchange priority, domain is willing to receive the mail address NS name server The most common record is a record, and the A record is parsed The server where the domain name is stored. In addition to the A record, if there is a mail service with the domain name mail address, you must have a MX record, and the mail server of the domain name must be parsed by MX. Such as: abc.com.cn 86400 in mx 1 mx.sina.net Checks if a domain MX record already exists: a very useful tool for performing DNS queries is nslookup, you can use it to query various DNSs data. In addition to the basic DNS queries that can be performed directly in the command line, the NSLookup will enter a interactive mode, where various types of DNS data can be queried here. DNS's name parsing data can have a variety of different types, with SOA type data for setting this zone parameter, with a type A-type data for the IP address corresponding to the name, with MX type data for setting mail exchange. These different types of data can be queried by NSLookup interaction mode, and you can use the set type command to set the corresponding query type during the query process.
