[COLOR="blue"] and then it replies to helo and i can use mail from:hello@hotmail.com and rcpt to:hello2@hotmail.com and data and write the mails but i cant close the writing and send the email using a as you sayso it answers: start mail input;end with <CRLF>.<CRLF> and i dont know what is that <CRLF>shit. any ideas[/COLOR]

CRLF stands for carriage-return/line-feed. When you see <CRLF> all that means to you is to press Enter. So
[CODE]<CRLF>.<CRLF>[/CODE]
really means is
[CODE]// press Enter to end up on the next line
. // type your period on this line then press Enter again
[/CODE]Oh, by the way, // designates comments, don't type them :D

when i try to put MAIL FROM: watever adress it says 50* invalid adress

You have to send the HELO or EHLO command before all that.

Most servers do not allow this anymore. To find one you can usually scan for open mail relays. Very cool for messing with someone and usually totally untraceable. Mail relays are a spammers best friend. Another type thats untraceable is the web based email.

can't connect anyone know why? i just get

blah blah blah on port 25: connect failed

Most popular email services (Hotmail, Yahoo!, Gmail, etc.) don't allow this sort of mail sending on their servers anymore.

you know of anyone that does?

I don't know of any that work, I just use online anon mail senders. Here's a nice list:

awsome thx

i get to the rcpt:adress .
and it just keeps saying relaying denied what does that mean

The mail server must be blocking you from sending mail. Try another server.

i tried quite a few and they just said "proper authentication required" is their any way round this. Or is their anyway to find a vulnerable server,
for Ethical reasons.

Just did some testing, and it seems email providers now only allow "trusted" IP addresses to send mail to their users. Gmail seemed to use some sort of whitelist of SMTP servers that it likes, and hotmail rejected IP addresses allocated by ISPs, I guess.
