Question

在CentOS7板上进行Exim设置时，我很难设置路由器或过滤器，以便基本上将所有传入的电子邮件发送到域名的Ruby脚本。

来自https://stackoverflow.com/a/32178818/10690518的分辨率似乎不再有效，/ etc / aliases方法似乎不起作用，并且Exim手册虽然相当详尽，但并没有使我达到可以创建的地步正确的路线。

这是我相当标准的Exim配置：

您必须添加路由器和传输。路由器应放置在路由器堆栈的顶部：

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

然后是运输-在运输清单中的任意位置：

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

someuser应该具有足够的权限来运行脚本。
包含所有标头的消息内容将传递到脚本的标准输入。
