“运行新别名”期间出错

Question

我需要一些帮助。

我从这里开始提到：在这篇文章中这篇文章

nitapika@nitapika-51:~$ echo bla | mail -s testmail lisa@you5.com

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：

nitapika@nitapika-51:~$ sudo apt-get -f install

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：

nitapika@nitapika-51:~$ sudo dpkg-reconfigure -plow postfix
/usr/sbin/dpkg-reconfigure: postfix is broken or not fully installed

不知道如何解决这个问题。我只需要 logcheck 应用程序向我发送异常。

Answer 1

1. 正确的mydomain在/etc/postfix/main.cf。

   04不是有效的域名 - 有效值是游览的条目domain.tld。

2. 也更改 的值valid_hostname。

   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.
