How to spoof Email address

What is Email spoofing..

Email spoofing is send an email to a specific recipient as it was sent FROM a different person's email address. If i want to send a fake mail to sample1@email.com as it was sent from sample2@email.com , this technique becomes handy.

Try this in your office.

Step 1

Open cmd and telnet your mail server with your outgoing mail port. Mostly the outgoing mail port should be 25 (SMTP port).

ex:

If the email to be spoofed is in the mail server on mail.office.com and it's outgoing mail port is 25 type as follows on cmd

telnet mail.office.com 25

and enter.



Then it will made the connection with mail server. If it's not made the connection error will comes say "Connecting To mail.office.com...Could not open connection to the host, on
port 25: Connect failed".

Step 2

Then type "HELO" (without apostrophized ) and enter to see the mail server response to our commands. Because some servers does not.



Then server will respond to it. If it's not it will that invalid command or something like that.

Step 3

What is the mail address that you are going to spoofed or in other words which mail address should be in the FROM field in the mail that you are going to send..

Let me get it as ab@office.com

Then type the following command to apply the sender address.

MAIL FROM:ab@office.com

And enter. You will see a reply message with "ok". Then the command is successful.

Step 3

Then we should give the email address of the recipient who get this fake email.

Let me get it as xy@office.com

command is..

RCPT TO:xy@office.com

And enter. You will see command succeeded with ok reply.

Step 4

Now we are going to add the information of this mail.

type DATA and enter.

now type as follows

date:DD month Y HH:MM;SS   press enter
from:ab@office.com                   press enter
to:xy@office.com                        press enter
subject:type the subject of the email       press enter

After you type the subject and pressed the enter you able to type your message to your recipient. (fake message).

After you finished the mail press enter and type . and press again enter.

Now the mail server will reply that it has accepted it or queued it.

After few minutes you will receive the mail.

This can't do to Yahoo because it's asking for authentication for send the mail. But for local mail servers this work well of it's not blocked for these commands.
