我已经将 Postfix 的默认发件人地址从[电子邮件保护]到[电子邮件保护]
我可以正常发送电子邮件，但当我检查邮件日志文件时，我看到一些“未找到“错误。
在/etc/邮件日志中：

/etc/postfix/通用
root [email protected]
一切正常，但仍然有这些错误。为什么邮件日志首先显示“未找到”，然后几行之后显示已找到？
答案1
似乎这些maps_find行是来自映射过程的调试信息，设置到您的 中/etc/postfix/generic。您的映射过程终止于
maps_find: smtp_generic_maps: hash:/etc/postfix/generic(0,lock|fold_fix): root
表示这封电子邮件将发送给 root
检查debug_peer_list并debug_peer_level禁用main.cf此选项（我个人将其注释掉并解决了我的日志过于冗长的问题）。您可以找到更多文档这里关于这些选项
