Exim - 发件人验证失败 - 拒绝 RCPT

Question

在检查 Exim 的日志消息时，我发现以下消息的许多条目“发件人验证失败”“拒绝 RCPT”...我不是 exim 专家...恐怕 Exim 没有将 100% 电子邮件发送给收件人，因为我们的电子邮件营销应用程序的打开率较低。

有人可以帮助理解这个日志消息吗？是我的服务器说“这里没有这样的用户”还是远程服务器？174.111.111.11代表我的服务器IP。谢谢

要调试此问题，请运行exim -bh 1.2.3.4. 这将打开一个模拟的 SMTP 会话，就像有人从该 IP 地址连接一样1.2.3.4，不过它还会输出大量调试信息（并且它实际上不会向任何人发送任何消息）。

开始输入 SMTP 命令 - HELO test，MAIL FROM: test@example.com然后输入RCPT TO: realuser@yourdomain。

输入命令后RCPT TO，您应该会看到相同的失败消息，但这次会有更多消息，您可以通过查看来找出拒绝发生的位置。

请记住包含HELO上面的命令，因为省略该命令可能会成为拒绝电子邮件的原因之一。
