Update 10/05/2026
This guide explains how to add a domain alias to a domain name.
Introduction
- A synonymous domain is a domain name that can serve as a secondary name for another domain.
- When a synonymous domain is added, it automatically inherits the content of the DNS zone of the main domain (including
MX,A, etc. records), as well as its Web and Mail hosting. - Alternatively, you can add an (domain) alias to a website or add a (domain) alias to a Mail Service.
