This guide explains how to block / blacklist email addresses or entire domains so that you are no longer bothered by specific unwanted emails in your Infomaniak mailbox.

You will learn that it is also possible to allow / whitelist addresses to bypass the anti-spam filter of your Infomaniak mailbox.

Preamble

• In addition to the Infomaniak anti-spam filter which eliminates the majority of unwanted emails as it evolves, Infomaniak offers two distinct lists that you can fill out as you wish:
  1. blocked senders:
     • blocked emails and domains are then directly treated as spam
  2. authorized senders (authorized to bypass the anti-spam filter):
     • authorized senders and domains will no longer be filtered by the anti-spam filter
     • the list of authorized senders is only active on the original recipient of each message; if the message is addressed to an address abc@domain.xyz and then redirected to def@domain.xyz, the anti-spam filter and the list of authorized senders must be configured for the address abc.
• These lists are specific to the email address on which the operation is performed.
• A Mail Service administrator can also apply these lists to the entire Mail Service, via the global configuration of a Mail Service (refer to this other guide).

A. Address/domain formats that can be used

As indicated in points 5 & 6 below, you can enter email addresses and/or domain names that will then be blocked or authorized on your mailbox.

To refine the precision of your filtering requests, the system supports partial searches through the use of wildcard characters * and ? . This character will automatically substitute any sequence of characters at its position, thus allowing flexible matches on incomplete strings.

Here are a few examples of entry formulations, for which you must of course replace the example domain (the-spam-domain.xyz) with the one that bothers you:

Block all email addresses from a domain name

*@the-spam-domain.xyz or toto*@the-spam-domain.com …

Block a domain and all its subdomains

toto@*the-spam-domain.xyz or toto@* …

B. Manage blocks or authorizations from the Infomaniak Web Mail app

Prerequisites

• Have permission to manage security: if you had been invited to the Infomaniak Web Mail app (online service ksuite.infomaniak.com/mail) to manage your address, it is possible that the Mail Service manager has removed this right from their admin account.

To block or authorize senders from the Infomaniak Web Mail app (online service ksuite.infomaniak.com/mail):

1. Click here to access the Infomaniak Web Mail app (online service ksuite.infomaniak.com/mail).
2. Click on the Settings icon ‍  at the top right.
3. Check or select the email address concerned in the dropdown menu of the left sidebar.
4. Click on Security:
   
5. To add a blocked sender (blacklisted), click on the Add an address button in the Blocked address box:
   
6. To add an authorized sender (whitelisted), click on the Add an address button in the Approved address box:
   
7. Fill in the fields as desired and/or according to the format indicated in point A above.

You can also block a sender directly from the received email:

1. Click here to access the Infomaniak Web Mail app (online service ksuite.infomaniak.com/mail).
2. Open the message from the unwanted sender.
3. Click on the ⋮ icon at the top right of the open message.
4. Choose Block the sender to add it directly to the list of blocked addresses:
   
   
   

If necessary, remove the address by returning to the Security tab.

C. Manage blocks or authorizations from Service Mail

To block or authorize senders from a 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 concerned.
3. Click on the email address concerned.
4. Click on the Security tab or from the left sidebar on Security:
   
5. To add a blocked sender, click on the Add an address button in the Blocked address box.
6. To add an authorized sender, click on the Add an address button in the Approved address box.
