In a DNS, MX-Entry stands for a Mail Exchange entry. It is a block of information in the MX section of the DNS Records that allows the brands to seamlessly communicate on behalf of their domain name.
For instance, you can contact us at [email protected] and it is only possible due to the MX Entries configured in our MX Records.
In simple terms, it allows you to send all the emails with your domain name at the end and allows your customers to send you an email to an email with the domain.
Why do you need an it?
Communication is an important aspect via building a brand. And, to perfectly communicate with the consumers, brands have been using brand-specific emails with the address pointing towards their domain.
This establishes a trust factor amongst the consumers that they are directly communicating with the brand. And, this experience is only possible due to the MX-Entries configured by the brands.
How does an MX-Entry work?
An MX-Entry acts as a bridge between the domain mail and the mail server. All the emails sent to [email protected] are routed to the mail server.
To understand how an MX Entry works, you’ll need to understand its format.
The example.com in the host section needs to be configured with the information about the root domain. It is to specify the root domain from which all the mails should be forwarded.
The value here refers to an mx-server’s address. It is configured to point to the preferred mx-server.
A priority number is used when the MX-Records have more than one server configured . It prioritizes the server based on the number.
The TTL here talks about the Time to Live. The Time to Live settings refer to the time limit for the information to live on a device or a remote server. Once, the time-frame exceeds the time limit, the data is then purged and refreshed with new information.

Do you remember the A-Record?, if not,we’d recommend for you to check out our content piece/podcast about an A-Record.
Here, you’ll need to specify the IP-address of your mail-server in the A-Record with the host name mail.
Once done, open your MX-Records table and add the following data and this will allow you to transfer all the emails to the recipients of your domain name.
