Domain name should generally set IP resolution and MX parsing, in which IP resolution typically includes three parsing records.
1, empty host name resolution: Add IP, the host name is left blank, IP resolution to http://www.aliyun.com/zixun/aggregation/14840.html "> virtual Host server IP." After parsing takes effect, you can access your virtual host directly with the top-level domain name, for example, you can enter abc.com access directly, provided you must bind abc.com this top-level domain in the virtual Host Control Panel.
2, www Resolution: When adding IP, the host name filled out WWW,IP resolution to the Virtual host server IP, after the resolution is effective, you can enter www.abc.com access to your virtual host, if you must bind www.abc.com
3, mail resolution: When adding IP, the host name filled out MAIL,IP resolution to the mail server IP, such as: 218.144.78.79 resolution after the effective, you can directly through the http://mail.abc.com access to your post office.
4. Mail records: After you add mail resolution records, you should also add a message record. Here, the host name should be left blank, which means that the post office for @abc.com is parsed. The level is generally set to 10, the corresponding mail host name to fill in mail. This mail host name is the mail resolution record you just added.
