更改 后，我的 postfix 安装在大多数消息上都无法记录myhostname。myhostname现在 不同于机器的 FQDN（和主机名），而以前它们是一样的。 更改后（出于其他原因），系统日志的传送和排队部分无法记录。 只记录了一些警告。
当我设置参数时，maillog_file所有日志都按预期出现在那里，并且像更改名称之前一样工作。然而，我注意到一件事：在日志行中，我看到的是myhostname而不是机器主机名。
我在 debian 上使用 rsyslogd，其（用于邮件）配置未修改。
我错过了什么？出于显而易见的原因，我希望它重新使用完整的 syslog 日志记录……

答案1
我终于找到了问题的原因......
在阅读了数百页之后，我发现日志记录是由 systemd-journald 完成的。systemd-journald 将日志转发到 (r)syslog。我的“问题”是设置MaxLevelSyslog为 的设置notice。我丢失的来自 postfix 的日志消息是级别 info。所以整个问题与 syslog 或 postfix 无关。希望这能对将来的某人有所帮助。
