Block email senders globally

This guide explains how to block (or allow) email senders globally on an entire Mail Service.

A Mail Service administrator can add email addresses or even entire domains to approved or denied sender lists, and these lists will be applied to all email addresses in a Mail Service (without modifying existing settings on each individual email address):

1. Log in to the Infomaniak Manager (manager.infomaniak.com) from a web browser like Brave or Firefox
2. Click on the icon in the top right corner of the interface (or navigate through the left side menu, for example)
3. Select Mail Service (under Collaborative Tools universe)
4. Click on the name of the relevant object in the displayed table
5. Click on Global Configuration in the left-side menu
6. Click on the Security tab
7. Click the Add an Address button in the Approved Address box to add an authorized sender
8. Do the same for senders to be blocked in the other box
   
9. Save to activate these lists for all email addresses in the domain
