Question

网站迁移到其他服务器之后，我们在通过SMTP（某些自定义的PHPMailer）使用PHP发送电子邮件时遇到了问题。 我们可以将电子邮件发送到大多数地址，但也有一些误码，如下所示。 anaybody有什么建议怎么了？是SMTP服务器问题还是脚本问题？ SMTP不应该返回一些特定的错误吗？

Answer 1

我认为您在这里混淆了两个问题。交付过程分为两个阶段-从PHPMailer到您的邮件服务器，以及从您的邮件服务器到收件人的邮件服务器。从您的第一个调试日志中，我可以看到第一阶段似乎运行良好-消息被正确接受。后两个示例来自邮件服务器的日志，而不是PHPMailer输出，因此它们发生在第二阶段。

这意味着您的问题不在PHPMailer或脚本中，而在邮件服务器或它自己的网络连接中。邮件服务器来来往往，而SMTP工作方式的一部分就是要解决错误，中断和延迟，这就是为什么在PHPMailer中使用本地邮件服务器是一个好主意的原因（正如您所做的那样）它可以处理这样的问题而无需您担心。这的确意味着您应密切注意邮件服务器的配置及其网络连接（通过日志），并且实现反弹处理程序也是一个好主意，这不是一件容易的事，以便您的应用可以访问听说此类延迟错误。

证书验证失败（我不确定您为什么将其描述为成功）可能是由过时的CA证书引起的；更新您的OS软件包，或安装受信任的根证书的全新副本（有关更多信息，请阅读PHPMailer故障排除指南）。最后一个看起来像一个不可靠的邮件服务器-您自己的邮件服务器应稍后再试发送-这就是邮件服务器的作用。

另外两件小事：这种问题只需要SMTPDebug = 2；更高的东西不必要地嘈杂。您还使用了旧版本的PHPMailer，因此请升级。

Answer 2

配置SMTP服务器时出错。服务器管理员更改了一些设置（不幸的是，他没有提供确切的解决方案）。

发送到某些地址时出现Smtp问题-错误：服务器未接受rcpt
