Help with Telnet SMTP Plz?

I was usint a tutorial i found on this site and it had a section about sending emails using telnet instead of a mail client. I tried to send an email to myself using telnet and it sent me an email, but it's completely blank. the from:, to:, subject:, and message that i entered are not there... anybody know why?

I'm only about 90% sure, but i think the following format should work.

HELO (your reverse)
MAIL FROM :<testaccount@test.com>
RCPT TO:<testaccount@test.com>
DATA
your message
QUIT

SMTP will only send mail if the server is setup as a relay.

If you want to give subject in your fake mail, just type in the data (where you write the text of the mail) subject: Iam testing

Output of a working example tested:

helo
250 mail.ahost.com Hello [127.0.0.1]
MAIL FROM:aperson@stuff.com
250 aperson@stuff.com....Sender OK
RCPT TO:anotherperson@hotmail.com
250 anotherperson@hotmail.com
DATA
354 Start mail input; end with <CRLF>.<CRLF>
Subject: stuff
From: aperson
To: stuff
Hello world!
.
Mail queued for delivery at some adress.

Note that that you don't have to find a server that allows relaying, if you telnet to the SMTP server of the host your "target" is with and send a spoofed email that way you're not sending an email to a different domain. This is applicable on the hotmail smtp servers for example.
