An email bomb is a form of denial-of-service attack in which an attacker sends a large volume of emails to a target email address or server in a short period of time. The goal of an email bomb is to overwhelm the target’s email system and make it unavailable to legitimate users.
Email bombs can be used to harass individuals or organizations, or to disrupt business operations. They can also be used to spread malware or viruses. In some cases, email bombs can even be used to bring down entire websites or networks.
