Hi,
I'm having trouble piping mail with exim. All I'd like to do is pipe
every incoming mail through a script. The script will output the
message (slightly modified, with an extra line or two). I am very new
to exim, and have no idea what to modify/add to exim.conf. Any help you
could provide will be greatly appreciated. I'm running on a server set
up for virtual hosting. Below is the exim.conf
Thank You again,
-Brandon
