Exim 4.91 - 将所有传入的电子邮件通过管道传输到脚本

Question

我很难想出一个路由器或过滤器来基本上将所有传入的电子邮件发送到一个域名到一个 Ruby 脚本，用于 CentOS7 板上的 Exim 设置。

的决议似乎不再有效，/etc/aliases 方法似乎不起作用，Exim 手册虽然相当详尽，但并没有让我达到这样的地步我可以创建正确的路线。



这是我相当标准的 Exim 配置：

您必须添加路由器和传输。路由器应该放在路由器堆栈的顶部：

begin routers
ruby:
  driver    = accept
  domains   = domain.tld : another.tld
  transport = ruby_script
. . . . .

然后是传输 - 在传输列表中的任意位置：

begin transports
ruby_script:
  driver  = pipe
  user    = someuser
  command = /path/to/the/script.rb

someuser 应该对运行脚本有足够的权限。
包含所有 headers 的消息内容将被传递到脚本的标准输入。
