Editing Spoofing attack (section)

=== E-mail address spoofing ===
{{Main|Email spoofing}}

The sender information shown in [[e-mail]]s (the <code>From:</code> field) can be spoofed easily. This technique is commonly used by [[E-mail spam|spammers]] to hide the origin of their e-mails and leads to problems such as misdirected [[Bounce message|bounces]] (i.e. e-mail spam [[backscatter (e-mail)|backscatter]]).

E-mail address spoofing is done in quite the same way as writing a forged return address using [[snail mail]].  As long as the letter fits the protocol, (i.e. stamp, [[postal code]]) the [[Simple Mail Transfer Protocol|Simple Mail Transfer Protocol (SMTP)]] will send the message.  It can be done using a mail server with [[telnet]].<ref>{{cite book|last=Gantz|first=John|title=Pirates of the Digital Millennium|year=2005|publisher=[[Prentice Hall]]|location=Upper Saddle River, NJ|isbn=0-13-146315-2|author2=Rochester, Jack B. }}</ref>
