[Exim] Multiple auto replies

I am having problems with sending vacation messages back to the sender.
Everything works, except it sends two identical replies back to the sender. I
am runnning exim 3.16. Here is my configuration file settings:

Transport section
vacation_user:
driver = autoreply
# user = ${local_part}
file = ${home}/vacation.txt
subject = "Re: $h_subject: {I am on vacation}"
to = ${reply_address}
from = ${local_part}

Director section
vacation:
 driver = localuser
 transport = vacation_user
 require_files = ${home}/vacation.txt
# do not reply to errors or lists
# senders = "! ^.*-request@.*:\
#             ! ^owner-.*@.*:\
#             ! ^postmaster@.*:\
#             ! ^listmaster@.*:\
#             ! ^mailer-daemon@.*"
# do not reply to errors and bounces or lists
# condition = "${if or {{match {$h_precedence:} {(?i)junk|bulk|list}} \
#                      {eq {$sender_address} {}}} {no} {yes}}"
 unseen
 no_expn
 no_verify
# user = ${local_part}
