There are many e-mail bombing tools and techniques freely available to the public.
There are also myriad reasons for cyber-citizens to send e-mail
bombs. For example, according to a recent survey [2], five percent
of the recipients of Internet junk mail retaliate by sending mail bombs
and executing other denial-of-service attacks.
In this section we review many of the techniques exploited and used
for creating powerful e-mail bombs on the Internet. These techniques
include chain bombs, error message bombs, covert
distribution and mail exploder exploitation. There are
other techniques as well. This section covers a large subset of
these e-mail bombing techniques.
