[請益] phpmailer發信問題

[chan15 (ChaN)]

我想要先寄出給指定收件者以後
把標題改掉寄給另一個副本收件者

include("lib/class.phpmailer.php");
$mail = new PHPMailer();
$mail->CharSet="UTF-8";
$mail->IsHTML(true);
$mail->Encoding = "base64";
$mail->From = "[email protected]";
$mail->FromName = "fromname";
$mail->Subject = "subject";
$mail->Body = "body";
$mail->AddAddress("[email protected]");
$mail->AddAddress("[email protected]");
$mail->Send();

$mail->Subject = "subject - copy";
$mail->AddAddress("[email protected]");
$mail->Send();

這樣直接使用的話，前兩個人也會收到改過得Email
但我似乎沒發現可以清除先前收件者list的語法
請問該怎麼做可以達到我的目的？
