[exim] Calling a Script from within exim

Hi,

I want to execute a script before delivering a mail locally. Pipe is not the right solution because it can be used in transports only (as I know). Also I wont use local_scan.

Requiered Flow:
- ACLs are passed
- Director is passed
- !! call a script !!
- deliver the message locally


Thanks in advance


best regards

Erwin
