Problems with black-lists

Hello,

I have Kannel version 1.4.0 and when I try to send a sms, I receive the 
error message:

"Number(s) has/have been denied by white- and/or black-lists."

But I don't understand this because I haven't got black-lists activated.
This is my conf file:

group = core
admin-port = 13000
admin-password = xxxxxx
admin-allow-ip = "127.0.0.1"
log-file = "/var/log/kannel/bearerbox.log"
log-level = 1
smsbox-port = 13001
box-allow-ip = "127.0.0.1"

# SMSC
group = smsc
smsc = at
modemtype = nokiaphone
device = /dev/ttyACM0
speed = 9600
keepalive = 5
pin = 9750
validityperiod = 5

group = modems
id = nokiaphone
name = "Nokia Phone"
detect-string = "Nokia Mobile Phone"
need-sleep = true
init-string = "AT"
keepalive-cmd = "AT"
enable-mms = true

# SMSBOX SETUP
group = smsbox
bearerbox-host = localhost
sendsms-port = 13013
#sendsms-chars = "0123456789 +-"
#global-sender = 12345
#log-file = "/tmp/smsbox.log"
#log-level = 0
access-log = "smsbox_access.log"
#white-list =

#reply-couldnotfetch =
#reply-couldnotrepresent =
#reply-requestfailed =
#reply-emptymessage =

# SEND-SMS USERS

group = sendsms-user
username = tester
password = tester
max-messages = 4
concatenation = 1
#user-deny-ip = ""
#user-allow-ip = ""

# SERVICES

group = sms-service
keyword = nop
text = "You asked nothing and I did it!"

# there should be default always

group = sms-service
keyword = default
text = "No service specified"

What is wrong?

Thank you.
