我需要一些帮助。
我从这里开始提到：在这篇文章中这个帖子
nitapika@nitapika-51:~$ echo bla | mail -s testmail [email protected]
The program 'mail' is currently not installed. You can install it by typing:
sudo apt-get install mailutils
然后安装mailutils：并收到此错误

然后尝试：

Postfix configuration was not changed. If you need to make changes, edit
/etc/postfix/main.cf (and others) as needed. To view Postfix configuration
values, see postconf(1).
After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

进而：

/usr/sbin/dpkg-reconfigure: postfix is broken or not fully installed
不确定如何修复此问题。我只需要 logcheck 应用程序向我发送异常信息。
答案1
正确
mydomain于/etc/postfix/main.cf。04不是有效的域名 - 有效值是旅游的入口domain.tld。valid_hostname也改变值。这只是一个警告，但主机名不是数字 - 使用输出
hostname --fqdn
之后执行：
sudo newaliases
sudo apt-get install -f
mydomain
The internet domain name of this mail system. The default is to use
$myhostname minus the first component, or "localdomain" (Postfix 2.3
and later). $mydomain is used as a default value for many other
configuration parameters.
myhostname
The internet hostname of this mail system. The default is to use the
fully-qualified domain name (FQDN) from gethostname(), or to use the
non-FQDN result from gethostname() and append ".$mydomain".$myhostname
is used as a default value for many other configuration parameters.
答案2
首先使用命令了解您的主机名：
hostname
编辑/etc/postfix/main.cf文件使用：
sudo nano /etc/postfix/main.cf
现在，改变：
myhostname =
到
myhostname = your_hostname #name of your hostname
现在重新启动系统并运行：
sudo apt install -f
答案3
在终端中输入以下命令：
$ postconf -d myhostname
现在编辑/etc/postfix/main.cf通过将文件更改为myhostname通过执行上一个命令获得的主机名。即更改：
myhostname = new_hostname
这new_hostname是执行命令时获取的主机名$ postconf -d myhostname
更改文件后，保存并运行以下命令：
$ /etc/init.d/postfix reload
$ service postfix reload
