Link an additional domain name to the Mail Service

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

Preamble

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

Add a domain name to the Service Mail

Prerequisites

• Own the new domain name (if necessary, it will need to be created beforehand).
• Familiarize yourself with the instructions in this other guide by applying the instructions corresponding to your situation (this is to ensure the domain name works when it is linked to your Service Mail).

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

1. Click here to access the management of your product on 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 sidebar:
   
4. Click on 'Domains linked to the service' in the left sidebar:
5. Click the blue button "Add a linked domain:"
   

6. It is possible to…
   

   1. … Search for an existing domain within the organization you are 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 located elsewhere).
   3. … Buy a new domain name.

    

a: The domain exists within the organization

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

It is done, the Mail Service now responds to a second domain name.

b: The domain exists but elsewhere (other Organization, other Registrar…)

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

Example of use

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

By adding the domain "usef.com" to the Mail Service "une-super-entreprise-familiale.com" you authorize all messages sent to contact@usef.com (the linked domain) to arrive among the messages already received by the address contact@une-super-entreprise-familiale.com.
