Spamming

Explanation:
Spamming — Involves repeatedly sending identical e-message to a particular address. It
is a variant of bombing, and is made worse when the recipient replies — i.e. recent
cases where viruses or worms were attached to the e-mail message and ran a program that
forwarded the message from the reader to any one on the user’s distribution lists. This
attack cannot be prevented, but you should ensure that entrance and exit of such mail
is only through central mail hubs.
