Link an additional domain name to the Mail Service

This guide explains how to have multiple denominations (everything that comes after the @ symbol of your email address) for an existing Mail Service by adding associated domain names to it.

Email addresses (existing and future ones) are automatically valid with all associated domains.

To completely transform and change the domain names of a Mail Service, read this guide (click here). To modify the part of your email address coming before the @ symbol, read this guide (click here).

Also note that you can rename your product in the Infomaniak Manager, but changing the name of a Mail Service has absolutely no impact on its emails. You need to act on the domain name.

Prerequisites

• Own the new domain name (if necessary, create it beforehand)
• Familiarize yourself with the instructions in this guide (click here) and apply the relevant instructions based on your situation (to ensure the domain name works when linked to your Mail Service)

Add a Domain Name to the Mail Service

Once the new domain name is ready to be used alongside the old one, you need to add it to the Mail Service:

1. Login to the Infomaniak Manager (manager.infomaniak.com) using a web browser like Brave or Firefox
2. Click on the icon in the upper right corner of the interface (or navigate using the left sidebar menu, for example)
3. Choose Mail Service (under Collaborative Tools)
4. Click on the name of the relevant object in the displayed table
5. Click on Domain Management in the left sidebar menu
   
   
6. Click on Domains linked to the service in the left sidebar menu
7. Click the blue button Add a linked domain
   
   
8. You can:
   
   1. Search for an existing domain within the organization you're connected to — this will link and automatically update the DNS zone of the added domain
   2. Add a domain name or subdomain to manually specify the domain name or subdomain to use (ideal if the domain name is hosted elsewhere)
   3. Buy a new domain name (read the prerequisites above)
   

a: the domain exists within the organization

1. Click on the proposed domain name
   
2. Click the blue button Link this domain
   

It's done; the Mail Service now responds to a second domain name.

b: the domain exists elsewhere

1. Enter the domain name to add
2. Enable DNS entry updates (if the domain name situation allows it, the DNS zone of the domain name will be automatically updated)
3. If point 2 above is active, then activate the replacement of potentially existing entries
4. Do not activate domain name reversal unless you want to set this new domain name as the primary one (this is mainly an administrative matter rather than technical)
5. Click the blue button Link this domain
   

Usage Example

The email contact@super-family-business.com is a long email address. The synonymous domain contact@usef.com is shorter and easier to remember.

By adding the "usef.com" domain to the "super-family-business.com" Mail Service, you allow all messages sent to contact@usef.com (the linked domain) to arrive alongside the messages that the contact@super-family-business.com address already receives.
