![postfix 中继 - 向不存在的邮件地址发送消息不会失败](https://linux22.com/image/778395/postfix%20%E4%B8%AD%E7%BB%A7%20-%20%E5%90%91%E4%B8%8D%E5%AD%98%E5%9C%A8%E7%9A%84%E9%82%AE%E4%BB%B6%E5%9C%B0%E5%9D%80%E5%8F%91%E9%80%81%E6%B6%88%E6%81%AF%E4%B8%8D%E4%BC%9A%E5%A4%B1%E8%B4%A5.png)
我有一个在层级服务器(Oracle 云电子邮件传递)上带有中继的 docker-mailserver。
当我向不存在的地址(例如,gmail)发送消息时,我会收到代码 250 Ok Sent(难道不应该是代码 550 吗?),但我希望在发件人邮箱中收到一封电子邮件,内容是“无法将消息发送到 {someaddresswichdoesnotexist}。”
以下是一些日志:

如何在本地设置上配置传送失败消息(我有一个 rainloop 客户端)?
