The URL forwarding function is the value-added service after the domain name provided by our company. The so-called URL forwarding is a special setting of the server, which will access the user of your current domain name to another network address you specify. For example, URL forwarding allows users to automatically turn to access http://www.mydomain.com / ... / ...

What is MX record?

Locating the mail server based on the restricted address suffix when email emails. For example, when the recipient is "user@mydomain.com", the system will perform MX record resolution in DNS "mydomain.com". If the MX record exists, the system forwards the message to the corresponding mail server corresponding to the MX based on the priority of the MX record.

What is generic domain name resolution?

For example, your domain name is abc.com, which is parsed to the same IP address under the mail.abc.com set. For example, customer setting mail.abc.com will automatically resolve to the same IP address with abc.com, the displayed page will be the same as ABC.COM.
