Mail bomb: An email message sent with the
intent to crash the recipient's mail server or mail reader. On many
systems, this can result in the cancellation of the bomber's account.
A person can unintentionally crash their message recipient's mail
server or mail reader by attaching files that are too large or that
are not supported by the recipient's mail server. So, don't send files
that require browser attachments, and if you have to send a large
file, you may want to zip it first!
