uchome中的发送邮件

1:将要发送的邮件加入到队列mailcron,mailqueue

//检查是否存在当前队列
	$cid = 0;
	$query = $_SGLOBAL['db']->query("SELECT * FROM ".tname('mailcron')." WHERE email='$email' LIMIT 1");
	if($value = $_SGLOBAL['db']->fetch_array($query)) {
		$cid = $value['cid'];
	} else {
		$cid = inserttable('mailcron', array('email'=>$email), 1);
	}
	
	if($cid) {
		//插入邮件内容队列
		$setarr = array(
			'cid' => $cid,
			'subject' => "product invite",
			'message' => "product invite",
			'dateline' => $_SGLOBAL['timestamp']
		);
		inserttable('mailqueue', $setarr);
	}

2:使用source/do_sendmail.php发送邮件，ssetcookie('sendmail', '1', 300);//用户每5分钟调用本程序

ssetcookie('sendmail', '1', 300);//用户每5分钟调用本程序
$lockfile = S_ROOT.'./data/sendmail.lock';
@$filemtime = filemtime($lockfile);

if($_SGLOBAL['timestamp'] - $filemtime < 5) exit();

touch($lockfile);

//防止超时
set_time_limit(0);

//获取发送队列
$list = $sublist = $cids = $touids = array();
$query = $_SGLOBAL['db']->query("SELECT * FROM ".tname('mailcron')." WHERE sendtime<='$_SGLOBAL[timestamp]' ORDER BY sendtime LIMIT 0,$pernum");
while ($value = $_SGLOBAL['db']->fetch_array($query)) {
	if($value['touid']) $touids[$value['touid']] = $value['touid'];
	$cids[] = $value['cid'];
	$list[$value['cid']] = $value;
}

if(empty($cids)) exit();

//邮件内容
$query = $_SGLOBAL['db']->query("SELECT * FROM ".tname('mailqueue')." WHERE cid IN (".simplode($cids).")");
while ($value = $_SGLOBAL['db']->fetch_array($query)) {
	$sublist[$value['cid']][] = $value;
}

//开始发送
include_once(S_ROOT.'./source/function_sendmail.php');
foreach ($list as $cid => $value) {
	$mlist = $sublist[$cid];
	if($value['email'] && $mlist) {
		$subject = getstr($mlist[0]['subject'], 80, 0, 0, 0, 0, -1);
		$message = '';
		foreach ($mlist as $subvalue) {
			if($subvalue['message']) {
				$message .= "<br><strong>$subvalue[subject]</strong><br>$subvalue[message]<br>";
			} else {
				$message .= $subvalue['subject'].'<br>';
			}
		}
		if(!sendmail($value['email'], $subject, $message)) {
			runlog('sendmail', "$value[email] sendmail failed.");
		}
	}
}
