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

Introduction

• Email addresses (existing and future) are automatically valid with all linked domains.
• To completely change and reverse the domain names of a Mail Service, please refer to this other guide.
• If you would prefer to modify the part of your email address that comes before the at symbol @, please refer to this other guide.
• Please also note that you can rename your product in the Infomaniak Manager, but changing the name of a Mail Service has absolutely no effect on its addresses; you need to modify the domain name.

Add a Domain Name to the Mail Service

Prerequisites

• Own the new domain name (if necessary, you may need to create it beforehand).
• Review the instructions in this other guide and apply the instructions that correspond to your situation (to ensure that the domain name works when it is linked to your 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. Click here to access the management of your product in the Infomaniak Manager (need help?).
2. Click directly on the name assigned to the product in question.
3. Click on Domain Management in the left-hand menu:
   
4. Click on List of domains linked to the service in the left-hand menu.
5. Click the blue Add a linked domain button:
   
6. It is possible to…
   
   1. … Search for an existing domain within the organization you are connected to; this will automatically link and 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 located elsewhere).
   3. … Buy a new domain name.

a: The domain exists at the Organization level

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

It's done: the Mail service now responds to a second domain name:

b: The domain exists but is registered elsewhere (another organization, another registrar...).

1. Enter the domain name to add.
2. Enable DNS record updates (if the domain name's status allows, the domain name's DNS zone will be updated automatically).
3. If the above point 2 is active, then enable the replacement of any existing entries.
4. Only enable domain name reversal if you want to define this new domain name as the primary one (this is mainly an administrative rather than a technical matter).
5. Click on the blue Link this domain button:
   

Example of use

The email address contact@une-super-entreprise-familiale.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 "une-super-entreprise-familiale.com" Mail service, you authorize all messages sent to contact@usef.com (the associated domain) will be among the messages received by the address contact@une-super-entreprise-familiale.com.
