All you need to know about MX record
The MX record is a fundamental component of the DNS (Domain Name System) that plays a crucial role in routing email messages between mail servers. In today’s article, we’ll take a deep dive into what MX records are, how they work, and why they’re important.
What is an MX Record?
An MX record (Mail Exchange record) is a type of DNS record that specifies a mail server responsible for accepting emails sent to a domain. MX records tell the sending server which mail server is responsible for handling the email for a particular domain, enabling the sender’s server to deliver the email to the correct address. These records are essential for a domain to be able to receive emails, as it helps to ensure that emails are delivered to the correct mail server. Having an MX record lets your domain easily connect with the correct mail server and ensures that all emails sent to it are correctly routed.
How to start managing MX records for your domain?
How does it work?
MX records work by assigning a priority value to each mail server listed in the record. The priority value determines the order in which mail servers should be contacted when delivering an email message. For example, if a domain has two MX records, the mail client will try to deliver the message to the server with the lowest priority value (highest preference) first. If that server is unavailable, it will move on to the next server on the list.
Why are MX Records important?
MX records are essential because they help ensure emails are delivered to the right destination. When an email is sent to a domain name, the sender’s mail server will look up the MX record associated with the domain name to determine which mail server should be used to deliver the email. If no MX record is associated with the domain name, the email will not be delivered. Without them, email delivery would be unreliable and unmanageable.
Benefits
MX records provide various benefits to help ensure emails are delivered correctly and efficiently. Some of the key advantages are the following:
Reduced Delivery Time: With an MX record, emails are routed directly to the correct server and mailbox instead of going through several hops. This reduces the amount of time it takes for the email to be delivered.
Increased Reliability: MX records provide a reliable way to ensure emails are delivered correctly, even if the sender’s server is down or has problems.
Improved Security: Having an MX record makes detecting and blocking malicious emails and spam easier.
Improved Performance: MX records allow email servers to route emails faster and more efficiently, resulting in improved performance.
