udsende mails

Hej

Jeg fandt dette script til at udsende mange mails på Zend.
Det fungerer fint, mit problem er dog, at SMTP serveren kræver godkendelse, er der nogen der kender til lignende scripts hvor dette er implementeret?

Her er scriptet
<?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($server='') { //din udbyders smtp server
        if (!$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");
        }
    }
//variablene for mailen sættes   
$from = "";
$tomail = "";
$toname = "GF";
$header = "";
$subject = "";
$body = "";
// SMTP forbindelsen åbnes og mailenesendes.
$smtp = new smtp_client();
$smtp->email($from, $tomail, $toname, $header, $subject, $body);
$smtp->send();
?>
