Exim actually forwards all mails to an exchange server.

I would like when a user test@??? received a mail, an automatic
respond send him :

Sorry the user to trie to join is no longer available. Thanks .....



My idea is to create a router like :

user_leave:
  driver = accept
  domains = +local_domains
  # user to put away message in a file called vacation.msg
  require_files = /root/user_leave.msg
  # do not reply to errors or lists or with ADV in the subject
  condition =  ${if or { \
                {match {$receiver_address} {test@???} \
                } {no} {yes}}
  no_expn
  # do not reply to errors or bounces or lists
  senders = ! ^.*-request@.*:\
            ! ^bounce-.*@.*:\
            ! ^.*-bounce@.*:\
            ! ^owner-.*@.*:\
            ! ^postmaster@.*:\
            ! ^webmaster@.*:\
            ! ^listmaster@.*:\
            ! ^mailer-daemon@.*:\
            ! ^root@.*
  transport = user_leave_transport
  unseen
  no_verify

######################################################################
#                      TRANSPORTS CONFIGURATION                      #
#...

user_leave_transport:
   driver = autoreply
   file =/root/user_leave.msg
   file_expand
   from = $local_part@???
   to = $sender_address
   subject = "Re: $h_subject"
   # text that will be included in message above
   text = "This is an automatic reply.  Please feel free to send
additional\n\
           mail, as only this one notice will be generated.\n\
           ================================================\n\n"

But of course it is not working.
I don t know if i need to create a local user to do this ,
if $receiver_address exit or if it is recipients, if i can place a message
in /root/user_leave.msg or in /home/exim or /home

Thanks for you help.
