在Ubuntu上配置邮件服务器的DKIM(DomainKeys Identified Mail)签名,可以按照以下步骤进行:

1. 安装必要的软件包

首先,确保你的系统已经安装了opendkimopendkim-tools。你可以使用以下命令来安装它们:

sudo apt update
sudo apt install opendkim opendkim-tools

2. 配置OpenDKIM

编辑OpenDKIM的配置文件/etc/opendkim.conf。你可以使用你喜欢的文本编辑器,例如nano

sudo nano /etc/opendkim.conf

在配置文件中,你需要设置以下参数:

示例配置:

Domain                  example.com
Selector                default
KeyFile                 /etc/opendkim/keys/example.com/default.private
Socket                  inet:12301@localhost

3. 生成DKIM密钥对

如果你还没有DKIM密钥对,可以使用以下命令生成:

sudo opendkim-genkey -t -s default -d example.com

这将在/etc/opendkim/keys/example.com/目录下生成私钥和公钥文件。

4. 配置DNS记录

在DNS管理面板中,添加一个TXT记录来发布DKIM公钥。TXT记录的名称应该是_domainkey.yourdomain.com,值应该是公钥文件的内容。

例如,如果你的域名是example.com,TXT记录的名称应该是_domainkey.example.com,值应该是:
