Mail Storm refers to

Mail Storm refers to

• A. High volume mail intended to cause a denial of service
• B. A flood of emails caused by Reply All behavior
• C. Forged sender headers to impersonate a brand
• D. A routine system alert distribution

Answer: (B)

A mail storm is a rapid flood of emails caused by many recipients replying to a single message, especially when people use Reply All. That behavior can set off a cascade where each reply prompts more replies, quickly overwhelming inboxes and mail servers. The option describing a flood of emails caused by Reply All behavior best matches this pattern, since the surge is driven by normal user activity and reply dynamics rather than a designed attack or spoofing. The other scenarios describe different issues: high-volume mail meant to cause a denial of service suggests a deliberate attack rather than a user-driven cascade; forged sender headers point to spoofing and impersonation; and routine system alert distribution is just regular, expected mail traffic.
