我正在尝试从我的 ubuntu (17.04) 服务器向 gmail、hotmail 发送邮件，但邮件被发送到垃圾邮件文件夹。我检查了 /var/log/mail.log，发现那里有关于 opendkim 的警告：
7 月 25 日 15:12:31 francooro postfix/cleanup[21233]: 警告：连接到 Milter 服务 inet:localhost:12301：连接被拒绝
我试图禁用 chroot 检查，我的防火墙已禁用，opendkim 服务已启动，但它似乎没有监听任何端口，因此我尝试添加另一个端口，但两个端口的连接都被拒绝。
我的配置是：

我的 chroot 现在是打开的，但我尝试禁用它，但没有帮助
我对密钥的权限如下：
drwxr-xr-x 2 root root 4096 Jul 24 15:59 ./
drwxr-xr-x 3 root root 4096 Jul 24 15:09 ../
-rw------- 1 opendkim opendkim 1679 Jul 24 15:09 mail.private

答案1
我在您的 /etc/opendkim.conf 中找不到三件事，例如：
Domain example.com
KeyFile /etc/opendkim/keys/example.com/dkim.private
Selector dkim
否则看起来与我的运行设置非常相似。
