So what is the right solution for such a situation? A **backup MX record** can deal with such a case efficiently. There are free backup MX services, like [NoIP backup MX](/content/backup-mx/noip-backup-mx) or [postfix backup MX](/content/backup-mx/postfix-backup-mx), that can configure a **backup email server** to receive and store the emails during an outage until the primary server gets back online. ![mx backup](https://media.mailhop.org/duocircle/images/2020/11/mxservice.png) ### Fundamentals Of Backup MX Record _MX (Mail Exchanger) can be understood as a type of DNS record_. A Domain Name System’s (DNS) preliminary work is to translate the names into IP addresses to make the network communication possible. The work of a particular MX record is to specify the mail server responsible for administering the emails in the domain. If an organization configures [multiple MX records](https://webx.net/mx-record-email-cpanel/) on a DNS server, then each MX record will be assigned a **priority level**. The email server’s order and the choice will be determined based on the MX record’s given priority. _It means that the MX record with low priority will work as a backup MX record if the primary mail server suffers downtime_. ### How Backup MX Record Works? _The backup MX record comes into play when the primary SMTP server goes offline_, and you are unable to receive any incoming emails as a result. - The organization has to configure a secondary MX record, which will work as the [backup MX](/content/backup-mx). - It has to set up the [secondary MX record](https://www.tppwholesale.com.au/blog/backup-email-service/) as a record of lower priority. - Whenever the primary server becomes inaccessible due to reasons like internet connection outage, patching of the mail server, server reboot, or any other reason, the [backup email server](/content/backup-mx/backup-email-server) will accept and queue the incoming emails on behalf of the primary server. - When the primary server returns into a normal state, the **backup SMTP server** will deliver the primary server’s queued emails. And you will not lose any of your important emails. _Any organization serious about email and business continuity must employ a backup MX record in the DNS server zone_. It will be yet another helpful tool for the disaster recovery and business continuity plan of the organization. Several providers also offer [free backup MX](/content/backup-mx/free-backup-mx) services, which users can opt for and test-and-try before going for the paid ones. ![backup email server](https://media.mailhop.org/duocircle/images/2020/11/duo-backup.png) ##### Join the thousands of organizations that use DuoCircle --- Find out how affordable it is for your organization today and be pleasantly surprised.
