Some legitimate emails can be categorised as spam because of the SPF check. Mailinblack anti-spam performs this check to prevent spoofing by a spammer from a sender domain. We thus verify that the sending IP address of the email is authorised to be sent for the sender domain.
Log in to your personal Mailinblack area and go to Access my admin area at the top right of your screen by clicking on your Surname and First name.
From your admin area, click the Emails menu.
Hover your mouse over the email and click on the following icon to trace the message:
If this is SPF blocking, the tracking will show this message:
An email can be classified as spam because the SPF control detected it as such.
You can notify the sender by informing them that their sending IP is not entered in their TXT field. If this is your domain, you can add the affected IP in the field.
If the sender is a contact that you cannot contact (example Amazon.fr or Booking.com), you can add the address, the domain or the sending IP to a list of exceptions. The SPF control will therefore not be performed on it.
However, we advise you to add the IP address, if it is fixed, or the email address as a security measure.
