Using telnet

HOW TO SEND A FAKE MAIL?

i'm going to give you the appended version, and facts that you will need to know
1.use your telnet program to connect to the victims server
How do you know the server? Most mail servers run on port 25. The name of the mail server is after the @ with mail appended to the front (except for big "on-line conglomerates"). So, your victim is asdf@thevictimserver.com . We then execute the command:
telnet mail.thevictimserver.com 25

for yahoo.com, telnet mx1.mail.yahoo.com 25 . Same with most other big companys.

When you connect, you will get something like:

220 YSmtp mta102.mail.scd.yahoo.com ESMTP service ready
ehlo
250-mta102.mail.scd.yahoo.com
250-8BITMIME
250-SIZE 10485760
250 PIPELINING
mail from:
250 sender ok
rcpt to:
250 recipient ok
data
354 Please start mail input.
subject: fake mail
from: no one bitch
to: a stupid, stupid man
date: none

hello friend.
.
quit

this is the total syntax. Let's review, now shall we? these are the commands issued in order.

ehlo
mail from:
rcpt to:
data
subject: data starts the mail input
from: this displays the from
to: this displays the to
date: date

make sure to hit enter twice after date to give it an "authentic" look. to end this message, leave a period "." on a line by itself and hit enter.
.
quit

and so the mail gets sent after you quit.
