Block / allow email senders
This guide explains how to block email addresses or entire domains to stop receiving unwanted mail, or conversely allow addresses to bypass your Infomaniak mailbox's anti-spam filter, thus always receiving their messages.
Preamble
- In addition to the Infomaniak anti-spam filter which eliminates the majority of unwanted mail as it evolves, Infomaniak offers two distinct lists that you can fill out as you wish:
- blocked senders:
- blocked emails and domains (blacklist) are then directly treated as spam…
- 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 on the original recipient of each message; if the message is sent to the address abc@domain.xyz and then redirected to def@domain.xyz, the anti-spam filter and the list of allowed senders must be configured for the address abc.
- blocked senders:
- 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.
- These lists are also automatically filled in based on your actions on emails at the anti-spam filter level.
Formats that can be used
Replace the example domain (the-spam-domain.xyz) with the one 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 certain email addresses from a specific domain
*example@the-spam-domain.xyz or john*@the-spam-domain.xyz
Block all incoming emails

- To add an authorized sender (whitelisted), click the Add an address button in the Approved address box:

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

- Open the message from the unwanted sender.
- Click on the ⋮ icon at the top right of the open message.
- 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.
