Change the domain name of a mail service

This guide explains how to replace the primary domain associated with a Service Mail in case you want to, for example, modify the spelling of everything after the @ in your email address (= the domain name).

Introduction

• You can also follow this procedure if your goal is to have completely new email addresses while keeping the history of your emails on Mail (since the email address will continue to exist, for example info@old-domain.xyz will become info@new-domain.xyz without modifying its content)
• In fact, it is not possible to simply change the spelling of the domain name in question; therefore, it is necessary to replace the current domain name associated with your email addresses with another domain name
• To simply add an additional domain name, read this guide
• To modify the part of your email address before the @, read this guide (click here)
• Note that you can also rename your product in the Infomaniak Manager, but changing the name of a Service Mail has no impact on its addresses; you need to act on the domain name.

Change the Domain Name of the Service Mail

Prerequisites

• Own the new domain name (if necessary, you will need to create it first)
• Review the instructions in this guide by applying the instructions relevant to your situation (so that the domain name works when it is linked to your Service Mail)

Once the new domain name is ready to be used instead of the old one, you need to add it to the Service Mail and then perform a switch:

1. Log in to the Infomaniak Manager (manager.infomaniak.com) using a web browser like Brave or Firefox
2. Click on the ‍ icon at the top right of the interface (or navigate using the left-hand menu, for example)
3. Select Service Mail (within Collaborative Tools)
4. Click on the name of the relevant item in the table that appears
5. Click on Domain Management in the left-hand menu
   
   ‍
6. Click on Domains linked to the service in the left-hand menu
7. Click the blue button Add a linked domain
   
    

8. You can:

   1. Search for an existing domain in 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 (see the prerequisites above)

   

a: the domain exists at the Organization level

1. Click on the proposed domain name
   
2. Click the blue button Link this domain
   
3. Click on the ⋮ icon next to the newly added domain name
4. Click on Set as primary domain (you need to have unlinked the synonym domain from the primary domain if there was an association before)
   
5. Confirm the switch and wait for the operation to complete
6. Click on the ⋮ icon next to the old domain name
7. Click Unlink domain
   
8. Confirm the disconnection

That's it, the Service Mail now responds to a new domain name.

b: the domain exists but elsewhere

1. Enter the domain name that will replace the current one
2. Enable DNS entry updates (if the domain name situation allows it, the DNS zone of the domain name will be updated automatically)
3. If point 2 above is active, then enable the replacement of any existing entries
4. Enable domain name switching (to avoid additional steps as in point "a" above)
5. Click the blue button Link this domain
   
6. Wait for the operation to complete
7. Click on the ⋮ icon next to the old domain name
8. Click Unlink domain
