This guide concerns the Discussion 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 discussion list service differs from classic messaging or a newsletter service by 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 moderator users to accept or reject registrations, send messages to subscribers, and then moderate member responses before publication.
  • Allow users to contribute to the discussion by replying to a single address that automatically redistributes the mail to other members.
  • Provide a simple and GDPR-compliant unsubscription option.
• Refer to this other guide regarding the service limits.

Access the discussion list

If the discussion 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 Discussion List in the left sidebar:
   

Creation and configuration of the discussion list

To create a new discussion list:

• Click the Start button…
  
• … or click the button above your existing lists:
  

Otherwise:

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

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 concerned (and which cannot be created on it, nor modified thereafter).
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 need to 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 subscription 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 one-way tool, such as information dissemination, or as a multi-way 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 addressed…
   • … to the sender with the source email address visible
   • … to the list (everyone receives) with the source email address visible
   • … 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 subscribing to the list.
12. Allows you to customize a message that will be automatically sent to an email address upon unsubscribing from the list.
13. Click the button to save.

Subscription (depending on the settings of point 6 above)

• Subscribers can sign up by sending a message to the email address in the form nom-de-la-liste-join@domaine-de-la-liste.
• 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 “mailto:” type link, which generates a new message that can be sent to the email address in the form nom-de-la-liste-request@domaine-de-la-liste with the subject accept email-address-subscriber and in the body of the message the line Approved: list-password, possibly adding a line stop to avoid the execution of other scripts, e.g. 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 reply (by clicking on the link to create a new reply email and pre-filled):
  
  • And in this case, the moderator receives the request in a second step, after validation by the subscriber, and must respond to it to validate the subscription (the simplest is always to click on the link):
    

Unsubscription

• Subscribers can unsubscribe by sending a message to the email address in the form nom-de-la-liste-leave@domaine-de-la-liste.
• Upon unsubscribing, a confirmation request message is sent to the user.
  • The user approves the request (always by clicking on the “mailto:” type link, which generates a new message that can be sent to the email address in the form nom-de-la-liste-request@domaine-de-la-liste with the subject the command specified in the confirmation email and an empty message body).

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 “mailto:” type link, which generates a new message that can be sent to the email address in the form nom-de-la-liste-request@domaine-de-la-liste.
• 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 option to subscribe to your list, you can generate a code that you simply need to insert 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 subscribing 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 subscribe multiple times without any specific message being displayed.

Error Management

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