Block / allow email senders

Update 09/28/2026

This guide explains how to block email addresses or entire domainsto stop receiving unwanted messages, or conversely, to allow certain addresses to bypass the anti-spam filter in your Infomaniak email inbox, ensuring that you always receive their messages.

 

Introduction

  • In addition to the Infomaniak anti-spam filter (❓: help), which eliminates the majority of unwanted emails as it evolves, Infomaniak offers two distinct lists that you can fill in as you wish:
    1. Blocked senders:
      • Emails and domains that are blocked (blacklist) are then directly treated as spam…
    2. Allowed senders:
      • Allowed senders and domains (whitelist) will no longer be filtered by the anti-spam filter…
      • The list of allowed senders is only active for the original recipient of each message; if the message is addressed to an address abc@domain.xyz and this is then redirected to def@domain.xyz, the anti-spam filter and the list of allowed senders must be configured for the address abc.
  • These lists are specific to the email address on which the operation is performed, but a Mail Service administrator can also apply these lists to the entire Mail Service via the Global Configuration of a Mail Service (❓: help).
  • These lists are also automatically populated based on your actions on emails at the anti-spam filter level.

 

Supported formats

Replace the example domain (the-spam-domain.xyz) with the domain that is bothering you and that you want to send directly to the Spam folder:

Block a specific email address

john.example@the-spam-domain.xyz 

Block all email addresses from a specific domain

*@the-spam-domain.xyz

Block specific email addresses from a particular domain

*example@the-spam-domain.xyz or john*@the-spam-domain.xyz

Block all incoming emails
