[exim] Exim4 with dspam looping

I have installed the debian dspam packages, using the (almost) default
configurations, and now I get a looping dspam call (from exim mainlog):

The transports look like this:

addspam:
driver = pipe
command = "/usr/bin/dspam --user
$local_part --mode=teft --class=spam --source=error"
current_directory = "/var/spool/dspam"
group = dspam
home_directory = "/var/spool/dspam"
log_output
message_prefix = ""
message_suffix = ""
return_fail_output
no_return_path_add
user = dspam

falsepositive:
driver = pipe
command = "/usr/bin/dspam --user
$local_part --mode=teft --class=innocent --source=error"
current_directory = "/var/spool/dspam"
group = dspam
home_directory = "/var/spool/dspam"
log_output
message_prefix = ""
message_suffix = ""
return_fail_output
no_return_path_add
user = dspam

# DSPAM
spamcheck:
driver = pipe
command = /usr/bin/dspam --mode=teft --deliver=innocent,spam --user
$local_part -bm %u
current_directory = "/var/spool/dspam"
group = dspam
home_directory = "/var/spool/dspam"
log_output
message_prefix =
message_suffix =
return_fail_output
no_return_path_add
user = dspam

The routers look like this:

======SNIP=========

# DSPAM
spamcheck_director:
  driver = accept
  check_local_user
  condition = "${if and {\
                         {!def:h_X-DSPAM-Result:}\
                 }{1}{0}}"
  headers_add = "X-DSPAM-Check: by $primary_hostname on $tod_full"
  transport = spamcheck
  no_verify

dspam_addspam:
driver = accept
check_local_user
local_part_prefix = spam-
transport = addspam

dspam_falsepositive:
driver = accept
check_local_user
local_part_prefix = falsepos-
transport = falsepositive

======SNIP=========

Can someone give me a hint what is running amok here?

Thanks a lot,

Arne
