萬網(wǎng)空間Linux系統(tǒng)如何發(fā)送郵件fsockopen

PHP程序在虛擬主機中可以通過調(diào)用fsockopen方式使用SMTP認證郵箱發(fā)信，相關(guān)程序代碼請參考：

<?
echo send_mail('此處為收件人郵箱','發(fā)信測試','測試測試測試測試測試測試');




<?


function send_mail($to, $subject = 'No subject', $body) {
        $loc_host = "test";            //發(fā)信計算機名，可隨意
        $smtp_acc = "



<?

test@hichina.com"; //Smtp認證的用戶名，類似fuweng@im286.com，或者fuweng
        $smtp_pass="test";          //Smtp認證的密碼，一般等同pop3密碼
        $smtp_host="mx.hichina.com";    //SMTP服務器地址，類似 smtp.tom.com
        $from="test@hichina.com";       //發(fā)信人Email地址，你的發(fā)信信箱地址
    $headers = "Content-Type: text/plain; charset=\"gb2312\"\r\nContent-Transfer-Encoding: base64";
    $lb="\r\n";                    //linebreak
           
        $hdr = explode($lb,$headers);     //解析后的hdr
    if($body) {$bdy = preg_replace("/^\./","..",explode($lb,$body));}//解析后的Body


 

        $smtp = array(

                //1、EHLO，期待返回220或者250
                array("EHLO ".$loc_host.$lb,"220,250","HELO error: "),
                //2、發(fā)送Auth Login，期待返回334
                array("AUTH LOGIN".$lb,"334","AUTH error:"),
                //3、發(fā)送經(jīng)過Base64編碼的用戶名，期待返回334
                array(base64_encode($smtp_acc).$lb,"334","AUTHENTIFICATION error : "),
                //4、發(fā)送經(jīng)過Base64編碼的密碼，期待返回235
                array(base64_encode($smtp_pass).$lb,"235","AUTHENTIFICATION error : "));
        //5、發(fā)送Mail From，期待返回250
        $smtp[] = array("MAIL FROM: <".$from.">".$lb,"250","MAIL FROM error: ");
        //6、發(fā)送Rcpt To。期待返回250
        $smtp[] = array("RCPT TO: <".$to.">".$lb,"250","RCPT TO error: ");
        //7、發(fā)送DATA，期待返回354
        $smtp[] = array("DATA".$lb,"354","DATA error: ");
        //8.0、發(fā)送From
        $smtp[] = array("From: ".$from.$lb,"","");
        //8.2、發(fā)送To
        $smtp[] = array("To: ".$to.$lb,"","");
        //8.1、發(fā)送標題
        $smtp[] = array("Subject: ".$subject.$lb,"","");
        //8.3、發(fā)送其他Header內(nèi)容
        foreach($hdr as $h) {$smtp[] = array($h.$lb,"","");}
        //8.4、發(fā)送一個空行，結(jié)束Header發(fā)送
        $smtp[] = array($lb,"","");
        //8.5、發(fā)送信件主體
        if($bdy) {foreach($bdy as $b) {$smtp[] = array(base64_encode($b.$lb).$lb,"","");}}
        //9、發(fā)送“.”表示信件結(jié)束，期待返回250
        $smtp[] = array(".".$lb,"250","DATA(end)error: ");
        //10、發(fā)送Quit，退出，期待返回221
        $smtp[] = array("QUIT".$lb,"221","QUIT error: ");

 

        //打開smtp服務器端口
        $fp = @fsockopen($smtp_host, 25);
        if (!$fp) echo "Error: Cannot conect to ".$smtp_host."
";
        while($result = @fgets($fp, 1024)){if(substr($result,3,1) == " ") { break; }}
       
        $result_str="";
        //發(fā)送smtp數(shù)組中的命令/數(shù)據(jù)
        foreach($smtp as $req){
                //發(fā)送信息
                @fputs($fp, $req[0]);
                //如果需要接收服務器返回信息，則
                if($req[1]){
                        //接收信息
                        while($result = @fgets($fp, 1024)){
                                if(substr($result,3,1) == " ") { break; }
                        };
                        if (!strstr($req[1],substr($result,0,3))){
                                $result_str.=$req[2].$result."
";
                        }
                }
        }
        //關(guān)閉連接
        @fclose($fp);
        return $result_str;
}
?>

以上代碼僅供參考，其中調(diào)用的smtp郵箱賬號和密碼以用戶實際郵箱賬號密碼為準
