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

Preamble

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

Modify the domain name of the Mail Service

Prerequisites

• Own the new domain name (if necessary, create it in advance).
• Refer to the instructions in this other guide by applying the instructions corresponding to your situation (this is so that the domain name works when it is linked to your Mail Service).

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

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 Add linked domain button:
   

6. 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 elsewhere).
   3. Purchase a new domain name (read the prerequisites above).

   

a: The domain exists at the Organization level

1. Click on the proposed domain name:
   
2. Click on the blue Link this domain button:
   
3. Click on the ⋮ icon to the right of the new added domain name.
4. Click on Set as primary domain (you must have dissociated the alias domain name from the primary domain name if there was an association previously):
   
5. Confirm the reversal and wait for the operation to complete.
6. Click on the ⋮ icon to the right of the old domain name.
7. Click on Unlink the domain:
   
8. Confirm the detachment.

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

b: The domain exists but elsewhere

1. Enter the domain name that will replace the current name.
2. Enable DNS entry update (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 enable the replacement of any existing entries.
4. Enable domain name reversal (to avoid additional steps as in point "a" above).
5. Click on the blue Link this domain button:
   
6. Wait for the operation to complete.
7. Click on the ⋮ icon to the right of the old domain name.
8. Click on Unlink the domain:
