Filtering spambots
HUMAIL settings
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.
