[exim] Destination address in a transport

Hi,

I need to find out how to put the destination email address into the my
transport. How do I do that?
Is that available in a ready-made variable?

my_router:
  driver = accept
  domains = ! +local_domains
  transport = my_transport
  no_more

my_transport:
  driver = pipe
  user = nobody
  command = /usr/bin/my_proggie - <destination-email-address>     <----
This is where I need to insert the recipient's email address
  return_fail_output

Thanks,
Thomas
