451 临时本地 - PHP 邮件程序

我使用 phpmailer 在网站上发送电子邮件，使用 SMTP 身份验证。但是最近我注意到我遇到了一个错误，

SMTP Error: The following recipients failed: [email protected]

然后我在邮件程序类中将调试变量设置为 true，我得到以下输出，基本上说这是一个暂时的问题，请稍后再试，我可以知道该怎么做才能解决这个问题吗？

SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is "220-servername ESMTP Exim 4.77 #2 Wed, 25 Jul 2012 08:59:03 +0530 "

答案1

如果说是暂时问题，您确实应该重试发送电子邮件，请稍后重试。

此外，您可以查看您的邮件服务器，也许您可​​以确定为什么服务器发送此错误消息。（这是服务器错误消息）

答案2

我猜想您的 /var 文件系统（或存储邮件队列的其他地方）已满。尝试发出一个命令df -h，看看您的文件系统是否已满。

答案3

sendmail、postfix 和 exim 等 SMTP 服务器软件旨在处理大量邮件，在出现临时问题时重试等。您的脚本不够智能，无法管理 SMTP 的所有复杂细节，也不应该如此。

如果它是如果您的服务器有问题，则需要查看服务器日志以找出拒绝邮件的原因。如果您使用的是第三方服务器，则需要联系第三方以了解邮件服务器的情况。
