Freemail is the name we give to big emails accounts providers. Those emails accounts dont require much to be created.
Gmail and Hotmail are two good examples of those.
It is very hard to create rules for those as the rules will meet a lot of legitimate senders but in the same time, those platforms are often used to send spams/phishings.
Detecting freemails is used in combination with other rules for a lot of different tests.
