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

    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.

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

    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,

    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.
