PHPMailer:亚马逊SES返回“；554交易失败:无效的电子邮件地址未公开的收件人:&”；

当使用PHPMailer通过Amazon SES向BCC地址发送电子邮件时，SES会返回以下错误。

554 Transaction failed: Invalid email address undisclosed-recipients:;.

只有当"收件人"字段中没有指定地址，并且填写了"未公开的收件人：；"时，才会发生这种情况。我尝试过只使用"收件人"字段中指定的地址发送电子邮件，效果很好。当发送地址在"收件人"字段且地址为密件抄送的电子邮件时，它也可以正常工作。

这是我用来将每个电子邮件地址添加为BCC的PHP代码，$Addresses是一个包含电子邮件地址的数组，没有键。

    if(is_array($Addresses))
    {
        foreach ($Addresses as $Email) {
            $Mail->AddBCC($Email);
        }
    }

这是PHPMailer的输出。

我还发现，一些人在使用SES的Postfix时会出现这个错误，但我还没有找到他们是如何解决这个问题的。
