autoresponse fails: mail -t recipient not specified.

   Just installed procmail on sparc solaris 8.
 attempting to use standard autoresponder

SHELL=/bin/sh
VERBOSE=on
LOGFILE=.pmdir/log

:0 h c
* !^FROM_DAEMON
* !^X-Loop: 
user(_at_)company(_dot_)com
| (formail -r -I"Precedence: junk" \
    -A"X-Loop: 
user(_at_)company(_dot_)com
" ; \
   cat .vacation.message) | $SENDMAIL -t

 but it will not respond to the sender.
 log claims
