Firstly this isnt my tutorial and i just found it on the net so please dont say that i stole someone elses tutorial. And I dont know if someone has posted this earlier too.
Well heres how it goes.

Firstly people should hav a good knowledge about telnet and how it is used.

Back to the tutorial , ok…now you can either download a telnet client , or use the windows version , this meaning , using command line interfaces….Were big hard hackers and we dont need no GUI ( Grafical User Interface ) to help us

Guessing you using micorosoft windows :

Right, to open the telnet aplication. Start => Run => Type : Telnet => A window Should Apear simlar to the command prompt screen.
You can press h to view a few basic telnet commands.

SMTP : This Stands for “Simple Mail Transfer Protocol” Basiclly a protocol for sending e-mail’s , you will need a SMTP server to send your email from, either from another company , or your own Internet service providers (ISP)
smtp port : 25

Heres a lsit of smtp servers:-

Note : Some ISP only allow you to use there SMTP servers , therefore blocking port 25 from using others.

ok! Now You Get A Basic understanding of all of this , lets get to the command line intnerfaces and conect to your chosen SMTP server !

As an Example I Will Be using Wanadoo’s SMTP service ( smtp.wanadoo.co.uk )

( Get Telnet Open And Runnning )

Telnet > open smtp.wanadoo.co.uk 25
^ ^
| |_____________ Mailing Port(25)
|
|______________ SMTP Server(smtp.wanadoo.co.uk

(It Should Say Conecting or somthing similar)

(obviously replace the example server with the SMTP server you’ve selected)

Now Type :

———————- ( press enter after every line )

HELO smtp.wanadoo.co.uk
MAIL FROM: madeupemailhere@somthinghere.com
RCPT TO: personsemailhere@somthing.com
DATA
from: madeupemailhere@somthinghere.com

Notes : Fill in the X’z With Random numbers to hide the senders Ip adress
Notes : Please Remember to put the ” . ” at the end ! ..Its Finishes The E-mail
