邮递员：是否可以重新发送退回的电子邮件？

我刚刚安装了一个邮件服务器发送通讯，但我（愚蠢）没有等待足够长的时间，以便新的专用子域传播通过DNSnetworking之前发送第一个，所以现在我有很多反弹的电子邮件： （（由于Sender address rejected: Domain not found (in reply to RCPT TO command) ）

由于大约一半的电子邮件经过了，是否有可能告诉邮递员重新发送退回的邮件，现在DNS问题解决了？

这是反弹的电子邮件之一的Postfix日志：

通常是错误信息 

 Sender address rejected: Domain not found (in reply to RCPT TO command)

表示这是暂时的错误，因为不存在的域。 DNS更改通常会在24小时内传播，默认情况下，postfix应自动重试此传递，直到maximal_queue_lifetime （默认值为5天）。

当你不小心将maximal_queue_lifetime设置为1小时，则postfix将在重试1小时后放弃 。 然后postfix会发送邮件反弹。

正因为如此，你需要重新发送邮件给邮递员。 如果您已经在邮递员列表中configuration了存档 ，那么您可以在那里检索原始邮件。
