MX(Mail Exchange) record is an important part of website' s DNS. It informs the entire internet where the mails for a particular domain has to be forwarded. Procedure to create MX Record for mail server in WHM/cPanel is explained in this tutorial.

During mail server installation, you may get an error that none of the MX records has been assigned for the respective domain. Here, we are installing Zimbra mail server and the following error appears. To overcome this error, change the MX record pointing to that particular domain.

In order to receive email from outside clients (for example if you want to receive email from gmail.com) you must have the MX record configured (needed also public IP), but if you want to set email communication only between your local users you don't actually need a public IP or MX record. but zimbra installation won't continue the installation without a MX record, so there is a trick you can configure your local DNS with a MX record pointing to your local domain name of your mail server.
