function send_mail($to,$subject,$body)
{
	/////////////Smtp信息,可以修改成你的,//////////
	$loc_host = "longbill";        //发信计算机名,可随意
	$smtp_acc = "longbill.mail";   //Smtp认证的用户名,
	$smtp_pass = "longbill";         //Smtp认证的密码,
	$smtp_host = "smtp.163.com";     //SMTP服务器地址,
	$from = "longbill.mail@163.com"; //要与smtp信息对应 ,否则会失败
	/////////////Smtp信息完//////////////////////////////////
	$headers = "Content-Type: text/plain; charset="gb2312"rnContent-Transfer-Encoding: base64";
	$lb="rn";                    //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(

	//9、发送“.”表示信件结束,期待返回250
	$smtp[] = array(".".$lb,"250","DATA(end)error: ");
	//10、发送Quit,退出,期待返回221
	$smtp[] = array("QUIT".$lb,"221","QUIT error: ");
	//打开smtp服务器端口
	$fp = @fsockopen($smtp_host, 25);
	if (!$fp) echo "<b>Error:</b> Cannot conect to ".$smtp_host."<br>";
	while($result = @fgets($fp, 1024))
	{
		if(substr($result,3,1) == " ")  break; 
	}
	$result_str="";
	//发送smtp数组中的命令/数据
	foreach($smtp as $req)

			}
			if (!strstr($req[1],substr($result,0,3)))
			{
				$result_str.=$req[2].$result."<br>";
			}
		}
	}
	//关闭连接
	@fclose($fp);
	if ($result_str==""){return "发送成功!!";}else {return $result_str;}

很简单阿,做一个循环就搞定的。

$mail_to=array("aaa@aa.com","bbb@bb.com");
$title="群发邮件标题";
$body="群发邮件征文内容";
foreach($mail_to as $to)
{
   send_mail($to,$title,$body);
}
