b. Company mail servers are better to be placed in DMZ than elsewhere in a network.

• DMZ provide more security.
• Mail servers is  individual email messages, as well as the user database built to store login credentials and personal messages, are usually stored on servers without direct access to the internet.
• An email server will be built or placed inside the DMZ in order to interact with and access the email database without directly exposing it to potentially harmful traffic.
