Mailbombing is the act of sending a large number of emails to a specific email address or server with the intent of disrupting their normal operations. This can be done for a variety of reasons, including harassment, revenge, or political protest.
Mailbombing can have a significant impact on its targets. It can cause email servers to crash, making it difficult or impossible for users to send or receive email. It can also lead to lost productivity, as employees may be unable to access their email accounts. In some cases, mailbombing can even be used as a form of cyberterrorism, as it can be used to disrupt critical infrastructure or government systems.
