Subject: [Exim] [long] mailman problem
hi,

environment is exim 3.35, mailman 2.0.8, as distributed in debian
woody (which means nothing special about exim, dunno about mailman but
i think that should be the same).

the exim configuration wrt mailman is the same as on the website:

#
# main
#
MAILMAN_HOME=/var/lib/mailman
MAILMAN_WRAP=MAILMAN_HOME/mail/wrapper
MAILMAN_UID=list
MAILMAN_GID=list

#
# transports
#
list_transport:
driver = pipe
command = MAILMAN_WRAP post ${lc:$local_part}
current_directory = MAILMAN_HOME
home_directory = MAILMAN_HOME
user = MAILMAN_UID
group = MAILMAN_GID

list_request_transport:
driver = pipe
command = MAILMAN_WRAP mailcmd ${lc:$local_part}
current_directory = MAILMAN_HOME
home_directory = MAILMAN_HOME
user = MAILMAN_UID
group = MAILMAN_GID

list_admin_transport:
driver = pipe
command = MAILMAN_WRAP mailowner ${lc:$local_part}
current_directory = MAILMAN_HOME
home_directory = MAILMAN_HOME
user = MAILMAN_UID
group = MAILMAN_GID

#
# directors
#
list_owner_director:
driver = smartuser
require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db
suffix = "-owner"
new_address = "${lc:$local_part}-admin@${domain}"

owner_list_director:
driver = smartuser
require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db
prefix = "owner-"
new_address = "${lc:$local_part}-admin@${domain}"

list_admin_director:
driver = smartuser
suffix = -admin
require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db
transport = list_admin_transport

list_request_director:
driver = smartuser
suffix = -request
require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db
transport = list_request_transport

list_director:
driver = smartuser
require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db
transport = list_transport


i've created a list with 'su - list -c "/usr/sbin/newlist teszt-l"'
then added a recipient as 'su - list -c "/usr/sbin/add_members -n - -c
n -w n teszt-l"'. i'm pretty sure this part is fine.

i'm trying to send a message to the list:

2002-04-05 00:11:11 verify failed for SMTP recipient
teszt-l@??? from <ice@???>
H=event-horizon.royalcomp.hu [195.70.35.140]

and obviously i get a bounce back stating:

  teszt-l@???
    SMTP error from remote mailer after RCPT
      TO:<teszt-l@???>:
    host tres.blki.hu [193.224.195.12]: 550 Unknown local part teszt-l
      in <teszt-l@???>


things get strange when trying to trace it from inside:

tres:~# exim -d0 -bt teszt-l@???
teszt-l@???
deliver to teszt-l in domain tres.blki.hu
director = list_director, transport = list_transport
tres:~#

(same result when testing as an untrusted user. this is good,
does as it's told to, see my config snippet below).

doing a test session:

and, actually, any hard i try, i cannot spot anything that would
render this address unverifyable (is there such a word?), nor can i
make it fail in test sessions.

if i send a mail from localhost to the list, it's delivered fine:

however, if i try from 195.70.35.140, it's rejected:

and it's accepted and actually delivered. could this probably be
related or similar to [Message-ID:
<Pine.SOL.4.44.0204031125100.29067-100000@???>],
which was about a verify loop in address test mode ? (3.35, and this
instance too, predates that posting by Philip).

as for the rest of my config, i have no_verify on two directors,
userforward and procmail, both of which are after the list* directors
in the config. other verify-related settings are

receiver_verify_hosts = ! 127.0.0.1 : ! 193.224.195.0/24 : *
receiver_verify_addresses = *
receiver_verify = true



i had it verified by a friend, just in case i'd be too tired. when run
"normally" in production, i'm starting this exim as "/usr/sbin/exim
-bd" (no automatic queue runs due to exiscan". for this test, i've
started it as "/usr/sbin/exim -d 11 -bd". mail to
<teszt-l@???> failed for this guy too.

i'm completely lost now. does anyone have an idea what to look at next
?

thanks a lot,
