[Exim] exim,exiscan,spamassassin and redirect message

I Am actualy using exim 4.41 with exiscan and spam assassin 3.00000 (CVS)

I am trying to redirect suspicious messages (reported as spam) to special
account, that works with :

/* -----------------
warn message = X-Redirect-To: spambox@???
     spam = nobody
------------------ */

and that is ok, but i would like to send also a small message to the user
with information that he recivied message but it was stored on safe account
(in case that he want it back anyway). But realy i don't know how to set
it??


Thanks for help.
