Filtering spambots

This article explains how to set up the control Humail control (turing test) to request authentication from the sender.

What you need to know:

Valid mail has a score of between 0 and 99.

Configuration :

To ward off attacks from spambots where anti-spam checks have not detected a threat.

Apply an authentication check based on a score from a threshold (depending on the activity of the email flow) of 0 to 50.

For example, below, the authentication request will be sent to the sender of the email scored from 50.

Note: a score of 0 applies permanent control to the sender who is not on the protected account's humail white or certified list.
