This guide explains how to activate the Infomaniak anti-spam filter which significantly reduces the number of unsolicited messages that can arrive in your Infomaniak mail address if you share it with third parties. The messages you really want to see quickly will no longer be drowned out among dozens of other unwanted messages, as the latter will be automatically placed in a folder specifically dedicated to this effect.

Preamble

• Spam is unsolicited mail, often of a promotional or fraudulent nature, aimed at promoting products, services, or carrying out online scams; a persistent problem since the beginnings of email that has evolved with communication technologies, prompting the implementation of strategies to combat this form of digital pollution.
• The filter is automatically activated when creating an email address within a Infomaniak Mail Service or when subscribing to a my kSuite / my kSuite+ offer.
• Emails placed in the Spam folder (or in the spam destination folder - read more below) are automatically deleted after 30 days.‍

Activate the option from the Web Mail app

Prerequisites

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

To access the settings of your Infomaniak mailbox:

1. Click here to access the Mail Infomaniak web app (online service mail.infomaniak.com).
2. Click on the Settings icon ‍ at the top right.
3. Check or select the relevant email address from the dropdown menu on the left sidebar.
4. Click on ‍ Filters and rules:
   
5. Enable (or disable) the spam filter option, the effect is immediate (wait for the on-screen confirmation message):
   
6. Simply click the toggle switch again to disable the filter; in this case, all future messages will go to the inbox, including messages with a header indicating a high spam score.
    

Activate the option from a Mail Service

To access the settings of your Infomaniak mailbox:

1. Click here to access the management of your product on the Manager Infomaniak (need help?).
2. Click directly on the name assigned to the product in question.
3. Click on the email address in question in the table that appears.
4. Click on Filters and rules in the left sidebar.
5. Enable the spam filter option, the effect is immediate:
   
6. It is enough to click the toggle switch again to disable the filter; in this case, all future messages will go to the inbox, including messages with a header indicating a high spam score (they can be processed downstream by your software/email client if it supports reading this type of header).

Note that you can activate it in bulk for multiple addresses at once.

Report spam or mark as false positive

If spam messages slip through or, conversely, if a valid email has been incorrectly classified as spam, you can intervene in a few clicks.

Prerequisites

• Check that the spam filter is active.
• For added security, enable the external mail tag.

To automatically move an email from your inbox that may have slipped through the spam filter into the Spam folder:

1. Click here to access the Mail Infomaniak web app (online service mail.infomaniak.com).
2. Select the message in the inbox then click on the Spam icon in the toolbar:
   
   
    
3. You can also open it and mark it as Spam at a later time:
   
   
    
4. Another option: open it and click on the action menu ⋮ on the right:
   
   

Once you have clicked on Mark as spam:

• The email is moved to the Spam folder (or to the manually defined folder)
• The sender's address is added to the blocked users list
• the filter is refined for better handling over time

Report a false positive

On the other hand, if you act on an email that has been wrongly marked as spam (false positive) by clicking on the "This is not spam" icon:

• The email is moved to the inbox…
• The sender's address is added to the list of authorized users…
• This also affects the filter and its criteria.

Customize the anti-spam filter

Change the location of spam

You can choose the default location of the folder where messages considered as spam will automatically go (similar to special IMAP folders).

Still under Filters and rules where you have activated the spam filter:

1. Click on Edit:
   
2. Click on the folder name to select another one (create a new one in advance if necessary):
   
3. Click on the Validate button.

Allow or block senders

You can specify in advance which senders should always go to the Spam folder (or vice versa): refer to this other guide for more information.
