我正在使用 sendmail 从我的 Rails 应用程序发送邮件。但是，在向特定用户域发送邮件时似乎发生了错误。来自 /var/mail/*** 的错误如下：

退回的电子邮件都来自同一个域，并且邮件正在成功发送到其他域。当我查找 SMTP 573 诊断代码时，我得到了这个"573 Internal server error, IP address related."。但我不知道这是什么意思。有人能帮帮我吗？
我运行了这些命令并运行它并得到了以下输出：

ping 似乎也正常工作：
# ping xxxxxxx.com

有人能帮我找出这个问题吗？
答案1
这意味着服务器在处理过程中遇到了与您的 IP 地址相关的内部错误。Ping 无关紧要 - 就像您早餐吃什么一样。显然 - 消息未传送到服务器。
可能是在告诉你滚开（例如：IP 地址因某种原因被列入黑名单）。可能是无法执行任何操作 - 服务器上的某些错误日志中会显示该错误。除非 (a) 你怀疑自己被列入黑名单，或者 (b) 你是服务器操作员，因此你可以检查并修复，否则这不是你的问题。
答案2
SMTP 中的任何 5xx 错误都意味着永久性传递错误。
这里有一组会话参数，它们可以与结果相关联
- 发件人地址（电子邮件）
- 收件人（电子邮件）
- 发送者 IP（您的服务器 IP）或主机名
您必须检查所有可能的变体，仅在会话之间更改一个参数（gmail 测试我不会接受，因为您会同时更改名称和服务器）并分析答案
在测试期间，我们会识别 - 是您对 *********.com.1.0001.arsmtp.com 的禁令还是配置错误（两种情况都有可能）
