我创建了一个脚本来安装 Postfix，它可以完美地与我的所有 Ubuntu 客户端配合使用，但不适用于我的 Fedora 客户端。
Fedora 客户端可以直接发送电子邮件至[电子邮件受保护]，但是当发送到 root 时，它应该被重定向到[电子邮件受保护]但被发送到[电子邮件受保护]
我一生都无法弄清楚为什么......这是配置和日志，如果有人能指出这个问题那就太棒了。

我注意到该行对我来说几乎看起来像“重定向/别名”，只是地址是错误的。to=<[email protected]>, orig_to=<root>,

答案1
嗯，我过去曾使用过这个，但这次尝试在设置 Postfix 时减少我的配置。我不知道为什么 Ubuntu 不需要它，但 Fedora 需要它，但这就是我修复它的方法。
/etc/postfix/main.cf：
canonical_maps = hash:/etc/postfix/canonical
/etc/postfix/规范：
root [email protected]
重新加载 Postfix 并测试！ -->postmap /etc/postfix/canonical && postfix reload
