php - Pear Mail - 收件人地址被拒绝 - 错误

Question

我在使用 Pear Mail 时遇到以下错误:

Notice: Error in sending mail: Failed to add recipient: user@domain.com [SMTP: Invalid response code received from server (code: 550, response: 5.1.1 : Recipient address rejected: User unknown in virtual mailbox table)] in /PEAR/PEAR.php on line 873

电子邮件未发送。其他电子邮件地址(例如 Gmail 和 Yahoo)工作正常。据我所知，它只会针对特定的电子邮件客户端出错。

我正在使用以下脚本发送排队的邮件:

require_once "Mail/Queue.php";

$db_options['type']        = 'mdb2';
$db_options['dsn']         = 'mysql://username:password@localhost/db';
$db_options['mail_table']  = 'mailqueue';
$mail_options['driver']    = 'smtp';
$mail_options['host']      = 'hostAddress';
$mail_options['port']      = 25;
$mail_options['localhost'] = 'localhost'; //optional Mail_smtp parameter
$mail_options['auth']      = false;
$mail_options['username']  = 'user@domain.com';
$mail_options['password']  = 'password'; 

$max_amount_mails = 100;
$mail_queue =& new Mail_Queue($db_options, $mail_options);
$mail_queue->sendMailsInQueue($max_amount_mails);

有没有人知道为什么特定地址会导致此错误？

我正在运行 PHP5.2/Apache2(CentOS 5.5)/Pear Mail 1.2.0/Pear Mail Queue 1.2.6/

谢谢

天哪，该错误消息的填充比错误还多!让我们把它分开一点。

Notice: 
Error in sending mail: 
Failed to add recipient: user@domain.com 
[SMTP: 
Invalid response code received from server 
(code: 550, 
response: 5.1.1 : 
Recipient address rejected: 
User unknown in virtual mailbox table)]

最后一行是我们唯一关心的。

SMTP 服务器查找您使用的地址，并提示无法找到该用户。换句话说 地址是假的并且正在被拒绝。
