在本地使用后缀

我在Chromebook上的Linux系统上进行了与此相同的操作。
在本地环境下设置可用邮件服务器的Postfix配置。

使用的环境

$ cat /etc/os-release 
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

安装

安装后缀。

sudo apt install postfix

我們將選擇 LOCAL 作為伺服器的選擇。

需要安装Telnet来进行测试。

sudo apt install telnet

环境设置

（省略）
#
home_mailbox = Maildir/

Postfix的重新启动

sudo systemctl restart postfix

创建用户

sudo adduser -uid 1220 holiday001

考试

telnet localhost 25

我将向holiday001@penguin.lxd发送电子邮件。

$ telnet localhost 25
