为什么我不能使用该mail命令阅读邮件？
（有几乎肯定是一个问题使用mail-stack-delivery配置，或者postfix，dovecot或者两者兼而有之，但我至少应该能够读取不来自 CLI 的邮件。

thufir@mordor:~$ ls -l /var/mail

接下来还有很多无关的细节：

为了简洁起见，我不会包括postconf输出，但doveconf会显示：
thufir@mordor:~$
thufir@mordor:~$ doveconf
# 2.2.18: /etc/dovecot/dovecot.conf
# Pigeonhole version 0.4.8 (0c4ae064f307+)

ID喜欢清除整个mail-stack-delivery包裹。

可能的解决方案：
thufir@mordor:~$
thufir@mordor:~$ sudo touch /var/mail/thufir
thufir@mordor:~$ sudo chown thufir:mail /var/mail/thufir
thufir@mordor:~$ sudo chmod o-r /var/mail/thufir
thufir@mordor:~$ sudo chmod g+rw /var/mail/thufir
thufir@mordor:~$
thufir@mordor:~$ mail
No mail for thufir
thufir@mordor:~$
