This book is for curious people that want to know how email security works, how to attack email protocols and how to defend from such attacks. It does not matter what your role is or if you do not work in IT security at all. I believe it can be of particular use for both people that have the email security of an organization to care for (e.g. security engineers, network and system administrators) and people that attack it for a living (e.g. red teamers and pentesters).

It is divided in three main topics:

A presentation of email security mechanisms
A set of attacks
A proposal for defense

The content is technical and use practical examples. All attacks described have been performed by the author (me) and part of it is based on professional penetration tests. Exercises are available at each chapter to familiarize the reader with hands-on cases.
