Picture of Telnet
Now we connect to the computer using telnet
in the terminal type
telnet <THE IP ADRESS> 25

and when it says connected type

mail from <anything@anydomain.any>

if there is no errror type

rcpt to <anyone@anydomain.com>

then type

data

look below for example

you may get an error like below if it appears the sites security is high enough to block you

The reason you keep getting "500 unrecognized command" errors is because the correct format for a mail to and rcpt to or anything would be

mail to: <anything@anydomain.com>
rcpt to: <anyone@yahoo.com>
If you leave out the : after "mail to" and "rcpt to" it wont work.

Please have correct information before misleading other members.

You can make the email to appear to come from any email
example
~HELO orgfree.com
~mail from <administrator@yahoo.com>
~rcpt to <c14rock1710042@yahoo.com>
~data
~ Hello,

~ please save it by visiting this site http://carbon14.ueuo.com
~ .
~message sent!

it will appear to com from the administrator but the truth is it was from you

You should lookup the MX record for the site your attempting to send mail to, A lot of domains use a separate host for their mail server. This can be done with nslookup or dig, There are also many web based tools to do DNS queries. Also you forgot to say HELO/EHLO before your mail from line.
