An MX record sets the mail server for a given domain name. If you have the domain myname.com, setting an MX record for myname.com will determine where mail for anyaddress@myname.com is sent. The mail server must be configured to accept mail for the domain name.

By default your domains with Neptune Web Hosting will have an MX record pointing to mail.(your domain). You can change this if you wish to use a different mail server. To do this you need to log into your control panel, select the domain that you want to change the MX record for and select DNS configuration.
