Exim4 DKIM 配置在 Debian Jessie 上不起作用

我在 Debian Jessie 上使用 exim4 4.84.2-2+deb8u1。下面我用 example.com 替换了一些域名。

dc_use_split_config='true'我在文件中有一个分割配置/etc/exim4/update-exim4.conf.conf。

在我的文件中/etc/exim4/conf.d/main/00_local_macros有：

DKIM_CANON = relaxed
DKIM_SELECTOR = 20161213
DKIM_DOMAIN = example.com
DKIM_FILE = /etc/exim4/dkim/example.com-private.pem

使用 root 权限运行后，update-exim4.conf我在文件顶部的/var/lib/exim4/config.autogenerated注释后有了上述配置。

DKIM_CANON = relaxed
DKIM_SELECTOR = 20161213
DKIM_DOMAIN = example.com
DKIM_FILE = /etc/exim4/dkim/example.com-private.pem

当然，该文件还有更多内容。

我使用 重新启动了 exim service exim4 restart。我注意到运行此命令时未显示正确的配置参数：

# exim -bP | grep example.com
primary_hostname = example.com
qualify_domain = example.com
qualify_recipient = example.com

当我发送邮件时，没有添加 DKIM 签名。

私钥的权限和所有者是：

# ls -la /etc/exim4/dkim/example.com-private.pem
-rw------- 1 root Debian-exim 887 Dec 13 10:23 /etc/exim4/dkim/example.com-private.pem

发送电子邮件时的日志是：

我如何让 DKIM 工作并且让 exim 识别我的配置？

答案1

解决方案是包含以下配置选项：

DKIM_PRIVATE_KEY = /etc/exim4/dkim/example.com-private.pem

并使用户成为密钥的所有者Debian-exim。
