This guide concerns the Mailing List service, which is only offered to Infomaniak users who have activated it in the past and for whom a tool migration was performed in early 2025.

Preamble

• The mailing list service differs from traditional email or a newsletter service by offering unique features:
  • Allow users to subscribe to a "subscription" via a simple registration form, the code for which is provided.
  • Allow one or more designated moderators to accept or reject registrations, send messages to subscribers, and moderate member responses before publication.
  • Allow users to contribute to the discussion by replying to a single address that automatically redistributes incoming messages to other members.
  • Provide a simple and GDPR-compliant unsubscribe option.
• Refer to this other guide regarding the service limits.

Access the mailing list

If the mailing list service has been activated in the past, it is accessible within your Mail Service:

1. Click here to access the management of your Mail Service on the Infomaniak Manager (need help?).
2. Click directly on the domain name assigned to the product in question.
3. Click on Mailing List in the left sidebar:
   

Creation and configuration of the mailing list

To create a new mailing list:

• Click the Start button...
  
• ...or the button above your existing lists:
  

Otherwise:

1. Edit an existing list by clicking on its name:
   
2. Click on its Configuration tab:
   

The parameters necessary for the proper functioning of the system are as follows:

1. A discussion list revolves around an email address that should not yet exist on the Mail Service of the domain in question (and which cannot be created on the latter, nor modified subsequently).
2. You can give a name to the list to identify it more easily if you have several or if the email address is not sufficiently explicit.
3. You can also add an additional description.
4. You must determine the email address(es) that will be moderators (= highest permission on the list).
5. You can set a language for your mailing list.
6. The configuration of "who can subscribe to the list" is important:
   • It is possible to specify that the user will have to confirm their registration themselves (in addition to a moderator).
7. The configuration of "who can write to the list" is just as important:
   • You can use the service as a unilateral tool, for example, information dissemination, or as a multilateral tool, information exchange, discussion including with non-members (with moderation)... 

8. Click on Advanced Options.
   
   

9. It is possible to configure whether responses should be sent...
   • ... to the sender with the visible source email address
   • ... to the list (everyone receives) with the visible source email address
   • ... to the list as coming from the list's email address itself
10. Allows you to limit the size of emails sent via the discussion list (especially in case of attachment).
11. Allows you to customize a message that will be automatically sent to an email address when registering on the list.
12. Allows you to customize a message that will be automatically sent to an email address when they unsubscribe from the list.
13. Click the button to save.

Subscription (depending on the settings of point 6 above)

• The subscribers can subscribe by sending a message to the email address in the form list-name-join@list-domain.
• They can also be manually subscribed by the moderator via the interface and in this case, they receive a notification email whose content can be customized.
• If the subscription made by a subscriber must be validated by a moderator, the latter receives an email:
  • The moderator approves the request by clicking on the link of type “mailto:” which generates a new message that can be sent to the email address in the form list-name-request@list-domain with the subject accept subscriber-email and in the body of the message the line Approved: list-password, optionally adding a line stop to prevent the execution of other scripts, for example in the case where there is a signature.
• If the subscription made by a subscriber must be validated by the subscriber himself, the latter receives an email to which he must respond (by clicking on the link to create a new reply email and pre-filled):
  
  • And in this case, the moderator receives the request at a second time, after validation by the subscriber, and he must respond to validate the subscription (the simplest is always to click on the link):
    

Unsubscription

• The subscribers can unsubscribe by sending a message to the email address in the form list-name-leave@list-domain.
• When unsubscribing, a confirmation request message is sent to the user.
  • The user approves the request (always by clicking on the link of type “mailto:” which generates a new message that can be sent to the email address in the form list-name-request@list-domain with the subject the command specified in the confirmation email and an empty body of the message).

Sending / receiving messages

• Each subscriber can create a Mail signature and choose their name when sending the email.
• A footer is automatically added to each message sent via the mailing list:
  
• See also the reply-to and from parameters at point 9 above.

Message moderation

• To reject a message, the moderator must click on the link of type “mailto:” which generates a new message that can be sent to the email address in the form list-name-request@list-domain.
• When a moderator is also a member of the list, they do not receive the messages they send themselves, but obviously receive those sent by other moderators.

Forms (subscription/unsubscription)

To offer a website visitor the opportunity to subscribe to your list, you can generate a code that simply needs to be inserted on your chosen site; example with Site Creator:

The Form tab allows you to specify the URL to which the user will be redirected after registering or unsubscribing:

• In case of an error when using the form, an error page may display the email address moderation-owner@list-domain allowing you to contact the moderators.
• A user already subscribed to the list can register multiple times without any specific message being displayed.

Error management

The system indicates the number of errors encountered by an address and the date:
