PHP中的退回邮件处理 - 是否有任何最新的解决方案？[已关闭]

反弹处理并非易事，因为您需要处理许多不同的服务器和响应。这包括那些由于您的电子邮件/主机/IP 已被列入黑名单/垃圾邮件评分而被错误配置和退回的服务器。而且由于“外出”自动回复而出现大量反弹。

我知道的一个简单的解决方案是将自己的标头放入消息中，以标识接收方地址和具体发送（令牌）。当它反弹时，可以基于此验证反弹。

另一种解决方案是将其他信息编码到发件人地址中，并相应地解析它以进行退回。为此，您需要了解电子邮件的工作原理，如果您需要退回邮件，这通常很有用。

• 使用PHP退回邮件处理？
• 用于分析查找退回邮件的 SMTP 日志的工具
• 如何在不发送电子邮件的情况下检查电子邮件地址是否存在？
• 指定电子邮件的退回邮件地址

关于SO有一些很好的答案（但我还没有找到这个答案），它详细介绍了这个主题的许多细节。如果我找到它，我会添加它。

一般的观点是，我不知道许多基于PHP的工具来处理退回邮件，我知道PHPList（用于邮件列表处理的PHP组件）在他们的存储库中有一些东西：

• 用于处理退回邮件的设置（上次有效快照）（最新等效项：退回邮件管理 - PHPList 手册)

编辑：具有非常翔实答案的相关问题是：

• 如何每周发送100，000封电子邮件？

编辑：它不多，只是一些链接：

我想知道为什么电子邮件退回没有标准，使您可以轻松识别退回邮件和退回原因 - 或者有吗？（像RFC一样）

有 RFC3834 - 对电子邮件的自动响应建议，由 RFC5436 Sieve 通知机制：mailto 更新。

RFC5321 简单邮件传输协议中也部分讨论了退回邮件，该协议清楚地给出了 MTA 必须在无法传递邮件时进行报告的原因。

主要问题是无法在SMTP中验证退回邮件地址（发件人），因此发送退回邮件会带来问题，即它可能发送给错误的人（Backscatter Spam）。

因此，可靠的邮件程序不仅可以检查退回邮件，还可以使用SMTP进行更多操作以获得一定的质量水平，请参阅：

• 退回地址标记验证 （BATV）
• 发件人策略框架 （SPF）

未交付报告的整个维基百科页面对于图片的第一次查看可能很有趣。

以下是我以前做过一次的事情。它可以持续捕获至少70%以上的退回邮件。

在发送的电子邮件中，放入一个自定义标头（如“x-email-check-id”），以便为发送的每封电子邮件提供唯一的标识符（可能创建一个GUID并将其存储在每个电子邮件的数据库中）

在服务器端，编写一个 cron 作业以定期从退回邮件地址下载电子邮件，并在回复邮件中查找此标头。这样，您就可以将退回邮件与发送的电子邮件进行匹配。这样，您可以确定此电子邮件已从您的发送中退回，并且不是垃圾邮件。

之后，在电子邮件内容中搜索特定关键字以确定退回邮件的原因。此关键字列表应经常更新，因为较新的电子邮件服务器返回不同的文本。但这是我使用的列表。
