Deliver emails to a program - pipe

Hi all,

I'm moving from an EXIM setup where I am able to set up an email alias to deliver emails to a pipe, This alias is routed to a pipe_transport

spreadsheet: /path/to/spreadsheet_reader.sh

When an email is sent to this alias, the program is called and the email sent via STDIN

I'm now moving to IceWarp on Linux. Is it possible to do the same thing?
