How to send anonymous emails from telnet
1) Open up MS-DOS/Command Prompt, by going to Run and typing cmd.
2) You should see a black window box. type in "nslookup".
3) At the very end of the message, there will be a ">". Type in "set type=mx"
4) Now another ">" will come up. Type in the name of the mail domain
of your victim. (hotmail.com, gmail.com, yahoo.com, etc.)
5) you should come up with a list of nameservers, MX servers, and
internet addresses. What we are interested in are the MX preferences.
Take note of the one with the highest MX preference. Now, type "exit".
6)Once you quit, type in this format: telnet [mail server] 25, where
telnet is the command, the mail server is the one with the highest MX
preference, and 25 is the port number.
Ex) telnet gsmtp183.google.com 25, where gsmtp183.google.com is a mail server for gmail.com.
7) If all is well, you should get a 220, meaning a greeting on a
connection. To make sure you are connected, type in "ehlo" or "helo".

quotes. Press enter. Type in "Reply- To: [your spoofed email address]"
without quotes. This is the most basic type.
