请问HN：在DNS问题后如何处理“被阻止”的邮件
几周前，我个人域名的根DNS服务器出现了故障（这是我自己的错误）。
我花了几天时间才弄明白……现在我收到了一些消息，称我的电子邮件在多个网站上“出现问题”，有些网站甚至拒绝给我发送邮件，尽管我的DNS已经修复。
请问我还有什么补救措施吗？
听起来答案是“没有，因为这是发件人特定的问题”。就我而言（例如），SendGrid需要我再次被列入白名单。

A couple of weeks ago, my root DNS server for my personal domain went offline (due to my own fault).<p>It took me a couple of days to figure out... and now I'm getting messaging that my email is "broken" across a number of sites a few that even refusing to email me even though my DNS is fixed.<p>Is there any recourse here?<p>It sounds like the answer is "no, there isn't any recourse because this is sender-specific". In my case (e.g.) SendGrid needs me to be whitelisted again.
