我在 Raspberrypi 3B+ 机器上使用基于 Debian Stretch 的 mit OpenMediaVault(ARM) 时遇到任何问题。
以下命令不会返回错误，也不会返回邮件：
root@raspberrypi:~# echo "Content" | mail -s "Subject" root
root@raspberrypi:~# mail
No mail for root
root@raspberrypi:~# cat /var/spool/mail/root
root@raspberrypi:~#
从邮件登录
cat /var/log/mail.log

如果有任何帮助，我将不胜感激
答案1
解决方案是 /etc/postfix/main.cf 中的以下几行：
myhostname = localhost
mydomain = localdomain
mydestination = $myhostname, localhost.$mydomain, localhost
inet_interfaces = $myhostname, localhost
mynetworks_style = host
default_transport = error: outside mail is not deliverable
重启postfix服务
root@raspberrypi:~# systemctl restart postfix.service
瞧
root@raspberrypi:~# echo Test | mail -s test root
root@raspberrypi:~# mail
Mail version 8.1.2 01/15/2001. Type ? for help.
