Explanation:

An email bomb or "mail bomb" is a malicious act in which a large number of emailmessages are sent to a single email address in a short period of time. The purpose of an email bomb is typically to overflow a user's inbox. In some cases, it will also make the mail server unresponsive. Email bombing is often done from a single system in which one user sends hundreds or thousands of messages to another user. In order to send the messages quickly, the email bomber may use a script to automate the process. By sending emails with a script, it is possible to send several thousand messages per minute
