Hi Gunnar,
As far no answer from the debian group :/
however,i've managed to get it work better... at least now i can see in the
logs that the kolabpolicy is called...
now, here's my config :
/etc/postfix/main.cf
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
# TLS parameters
smtpd_tls_cert_file=/var/smtp/mail.pem
smtpd_tls_key_file=/var/smtp/mail.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.
myhostname = myhost.mydomain.org
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = myhost.mydomain.org, mydomain.org, localhost
relayhost =
mynetworks = 127.0.0.0/8
mailbox_command = procmail -a "$EXTENSION"

mailbox_transport = kolabmailboxfilter
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
# Support broken clients like Microsoft Outlook Express 4.x which expect
AUTH=LOGIN instead of AUTH LOGIN
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_mynetworks,
permit_sasl_authenticated,reject_unauth_destination,
reject_unlisted_recipient, check_policy_service unix:private/kolabpolicy
#smtpd_sender_restrictions = permit_mynetworks, check_policy_service
unix:private/kolabpolicy

and finally,
/etc/kolab/kolab_smtpdpolicy.conf

basedn: dc=mydomain,dc=org
binddn: cn=manager,cn=internal,dc=mydomain,dc=org
bindpw: mypassword
domain: mydomain.org
allow_unauth: 1
permithosts: localhost
Do these config files seem good to you?
i can't understand why when putting allow_unauth: 0 then i get the following
error when i send a mail from an external user to a kolab user
Feb 20 21:47:47 mailhost /usr/sbin/kolab_smtpdpolicy[18637]: Checking
sender="me at gmail.com", recipient="kolabuser at mydomain.org", username="",

Feb 20 21:47:47 mailhost postfix/smtpd[18631]: NOQUEUE: reject: RCPT from

Invalid sender; from=<me at gmail.com> to=<olabuser at mydomain.org> proto=ESMTP
helo=<smtp.gmail.com>
When i send a mail directly from Horde (which is on the same server) the
policy is not called to treat the message... I suppose that it has something
to do with the order of parameters in smtpd_recipient_restrictions ?
Many thanks for your help,
Eleni
