Telnet
ever wondered how to "fake" emails? well here is an introduction to telnet - which is a text-based program that allows you to communicate with other remote computers. (like mail servers as I will show in this tutorial.) Now a word of warning, This is not a method of faking mail that will want to use in situations where what you say in the message could potentially get you jailed, because the mail, while having a fake sender address, still has your IP address on it, so dont misuse it.
First, know the mailserver of your intended victim, for this tutorial, you can send forged mail to the BlackDeskCustom mailserver mail.blackdeskcustom.com to the address resources@blackdeskcustom.com , if you include your email address, I will email you to tell you that your forged mail attempt was successful!
Step 1
In windows, start > run and type telnet. In linux drop to console (hit Ctrl + alt + F1/Fn) you will be greeted with this wonderful display
Step 2
now that you have telnet up and running, type in "open", the program will now ask you where you would like to open a connection to, for this tutorial, try the BlackDeskCustom mail servers (if you include your email address in your mail, i will reply to you - Don't worry, your privacy is assured) Put in "mail.blackdeskcustom.com" followed by a space, then the port number (try 25)
Step 3
after connecting, the remote computer will notify you that its ready to accept requests. you should now see 220 <hostcomputername>. Now be polite and say ehlo to the remote computer. Type in "ehlo" and see what happens.(yes I have spelt it correctly for all you smart alecs out there).
