Problemer med en mail class login

Goddag derude jeg faldt over denne clas i nogle spørgsmål om det sammen men jeg har lidt problemer med den:

<?php
class smtp_client {
    var $connection;
    var $server;
    var $elog_fp;
    var $log_file='./smtp_client.log';
    var $do_log=true;


    // default constructor
    function smtp_client($server='customer-smtp.one.com') { //din udbyders smtp server
        if (!$server) $this->server="localhost";
        else $this->server=$server;
       
        $this->connection = fsockopen($this->server, 25);
        if ($this->connection <= 0) return 0;

        $this->elog(fgets($this->connection, 1024));
        $this->elog("HELO xyz\r\n", 1);
        fputs($this->connection,"HELO xyz\r\n");
        $this->elog(fgets($this->connection, 1024));
        }

    function email($from_mail, $to_mail, $to_name, $header, $subject, $body) {
        if ($this->connection <= 0) return 0;

        $this->elog("MAIL FROM:$from_mail", 1);
        fputs($this->connection,"MAIL FROM:$from_mail\r\n");
        $this->elog(fgets($this->connection, 1024));

        $this->elog("RCPT TO:$to_mail", 1);
        fputs($this->connection, "RCPT TO:$to_mail\r\n");
        $this->elog(fgets($this->connection, 1024));

        $this->elog("DATA", 1);
        fputs($this->connection, "DATA\r\n");
        $this->elog(fgets($this->connection, 1024));

        $this->elog("Subject: $subject", 1);
        $this->elog("To: $to_name", 1);
        fputs($this->connection,"Subject: $subject\r\n");
        fputs($this->connection,"To: $to_name\r\n");

        if ($header) {
            $this->elog($header, 1);
            fputs($this->connection, "$header\r\n");
            }

        $this->elog("", 1);
        $this->elog($body, 1);
        $this->elog(".", 1);
        fputs($this->connection,"\r\n");
        fputs($this->connection,"$body \r\n");
        fputs($this->connection,".\r\n");
        $this->elog(fgets($this->connection, 1024));

        return 1;
        }


    function send() {
        if ($this->connection) {
            fputs($this->connection, "QUIT\r\n");
            fclose($this->connection);
            $this->connection=0;
            }
        }

    function close() { $this->send(); }


    function elog($text, $mode=0) {
        if (!$this->do_log) return;

        // open file
        if (!$this->elog_fp) {
            if (!($this->elog_fp=fopen($this->log_file, 'a'))) return;
            fwrite($this->elog_fp, "\n-------------------------------------------\n");
            fwrite($this->elog_fp, " Sent " . date("Y-m-d H:i:s") . "\n");
            fwrite($this->elog_fp, "-------------------------------------------\n");
            }

        // write to log
        if (!$mode) fwrite($this->elog_fp, "    $text\n");
        else fwrite($this->elog_fp, "$text\n");
        }
    }

mysql_connect("localhost", "***" ,"***") or die (mysql_error());
mysql_select_db("***") or die (mysql_error());

$res = mysql_query("select til, navn from test") or die (mysql_error());

$from = "test@kalendersystem.dk"; //din egen mail :-)
$header = "Content-type: text/plain; charset=ISO-8859-1";
$subject = "Test af fsockopen()";
$body = "Dette er en test";

$smtp = new smtp_client;
$smtp -> smtp_client();

while (list($til, $navn) = mysql_fetch_row($res)) {
  $smtp->email("$from", "$til", "$navn", "$header", "$subject", "$body");
  }

$smtp->send();
mysql_close();
?>

I min database har jeg laver 2 felter så den kører 2 gange det ser også ud til at virke, men den sender ingen mails...

Den snakker om at jeg ikke er logget ind? Det er som om den ikke mener jeg har indtastet en rigtig "fra mail" hvis jeg forstår den korrekt...
