When someone sends multiple copies of the same message, or file, to another person with the purpose of filling their EMail box up fully Against most ISPs terms
To send, or urge others to send, massive amounts of electronic mail to a single system or person, with intent to crash or spam the recipient's system A successful mail bomb may cause the victim's disk quota to be exhausted, the disk holding his mailbox to fill up, or his computer to spend a large proportion of its time processing mail Mail-bombing is sometimes done in retaliation against someone persistently abusing Usenet and violating netiquette While it may inconvenience the intended victim (if they gave their real address), it will probably also inconvenience other users and administrators of the computers and networks involved Mailbombing is thus a serious offense itself
sending hundreds or thousands of messages to someone you think deserves punishment for their transgressions against the Internet Highly discouraged for obvious reasons
To send a large number (typically many thousands) of messages to a user's e-mail account, for malicious purposes The action will typically have one of three effects First, the receiving system may crash Second, the receiving system will fill up and will thus refuse to accept genuine messages Third, any genuine messages will be difficult to spot because the mail box is so full of junk messages, each of which will appear to come from a unique user on a unique site (mail bombers typically exploit system security in order to send messages with forged headers)
The act of sending massive amounts of email to a single address, with the malicious intent of disrupting the recipient's computer Mail bombing is considered a serious breach of Netiquette and is illegal in some countries
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!
An e-mail message sent with the intent to crash the recipients mail server or mail reader Mail bombing is a form of electronic harassment and can on many systems result in the cancellation of the bomber's account
