Today, email is an important part of people's daily lives. Several open-source programs can be used to install a mail server to meet all the needs of its users. Postfix, Dovecot, and Roundcube are some well-known technologies that have been developed with a security emphasis. The present thesis describes the installation of these technologies as well as their configuration to achieve the best possible security. The first step is to report common attacks which a mail server may encounter and implement countermeasures. The paper also presents additional techniques for hardening mail servers as a result of increasing countermeasures. Aside from the implementation of countermeasures in such systems, Wazuh also provides specific solutions for monitoring the mail server live and informing the user of security events. Furthermore, a method for verifying a system's successful insurance is presented. Lastly, conclusions are provided regarding how to make email servers more secure.
