Un point important a precise avant : Maildrop n’est pas compile par default avec le suport LDAP. Dans les nouvelles version le support LDAP a disparu. Je ne me suis pas encore penche sur la configuration avec le authdeamon. En attendant il ne faut surtout pas mettre maildrop a jour.

Fichier de configuration ldap, maildropldap.config :

# Sample maildropldap.conf file, to enable virtual users via
# LDAP in maildrop.  
#
# In order for the LDAP extension to work properly a few
# attributes must exist in the LDAP entries.
#
# You may redefine the actual names of these attributes, as they appear
# in your LDAP object class further down in this config file.
#
# The attributes are:
#
# mail - The full email address of the user (ie user@yourdomain.com)
#        This is the primary attribute searched upon by maildrop.
#
# maildir - The location (full path including name) of the users
#           mail directory (Maildir)
#
# homedirectory - The location (full path including name) of the 
#                 users home directory.  This may be the same as the
#                 users maildir.
#
# uidnumber - The uid of the user that owns the mail files for 
#             this user.  This may be a specific uid per user, 
#             or a single uid for every user (full 'virtual' user 
#             configuration), or a combination.
#
# gidnumber - The gid of the user that owns the mail files for 
#             this user.  This may be a specific gid per user, 
#             or a single gid for every user (full 'virtual' user 
#             configuration), or a combination.
#
# quota     - *OPTIONAL* The quota for this user.  If blank, or
#             non-existent defaults to no quota.
#
# A sample LDAP entry is given at the end of this file.
#
# --- Actual configuration begins here -----------------------------

# hostname - host name of your ldap server
hostname	localhost

# basedn - base DN by which to search for LDAP entries
basedn		o=mail

# filter - optional, addition filter to add to
# default 'mail=<email address>'
# 'emailstatus' is an attribute which could be created in the
# LDAP entry to set whether or not the user is allowed to
# receive email on this box.. just an example
#
# this option can be left out and the default search would 
# just be 'mail=<email address>'
#filter		&(&(objectclass=vmailAccount)(emailstatus=active))
filter		&(AccountStatus=active)

# binddn, bindpw - optional, binddn and password if your ldap server
# requires you to authenticate before searching
binddn		cn=reader,o=mail
bindpw		secret

# timeout - specifies maximum time ( in seconds ) to wait for a response
# from the LDAP server
timeout		5

# search_method - used to specify whether to search on the users id, or
# email address, and may be either 'mail' or 'uid'
#
# if set to 'mail' (default) then to deliver mail to a user you must
# specify the entire email address:
#   ie.   maildrop -d joeuser@domain.com
#
# if set to 'uid' then to deliver mail to a user you need only specify
# the users id (username)
#   ie.   maildrop -d joeuser
#
search_method		mail

# default_uid - default uid (number only) to use incase uidnumber attribute not
# found in users ldap entry
default_uidnumber	5000

# default_gid - default gid (number only) to use incase gidnumber attribute not
# found in users ldap entry
default_gidnumber	5000

# LDAP Field definitions
#
# This section allows you to specify the actual attributes you
# use in your LDAP object class
# 
# The example attribute mapping shown below is also the default
# mapping used by maildrop in the case that any are missing

# MAIL_ATTR - LDAP attribute which contains the users complete email address
mail_attr		mailAlternateAddress

# UID_ATTR - LDAP attribute which contains the users name (w/o domain)
uid_attr		uid

# UIDNUMBER_ATTR - LDAP attribute which contains the system uid to deliver
# mail as
#uidnumber_attr		uidnumber

# GIDNUMBER_ATTR - LDAP attribute which contains the system gid to deliver
# mail as
#gidnumber_attr		gidnumber

# MAILDIR_ATTR - LDAP attribute which contains the path to the users
# custom maildir
maildir_attr		mailMessageStore

# HOMEDIRECTORY_ATTR - LDAP attribute which contains the path to the users
# home directory
homedirectory_attr	mailMessageStore

# QUOTA_ATTR - LDAP attribute which contains the users quota
#quota_attr		mailQuota

Ainsi que le fichier maildroprc :

# Global maildrop filter file

# Uncomment this line to make maildrop default to ~/Maildir for
# delivery- this is where courier-imap (amongst others) will look.
#DEFAULT="$HOME/Maildir"

#logfile "/tmp/maildrop.log"


if (/^From: report@idbconsulting/) 
{
#    log "Report"
#    log "Report $HOME $DEFAULT"
    `maildirmake -f Report "$DEFAULT"`	
    if (/^Subject: VIRUS/) 
    {
     `maildirmake -f Report.Virus "$DEFAULT"`	
     to "$HOME/.Report.Virus"
    }
    if (/^Subject: SPAM/) 
    {
     `maildirmake -f Report.Spam "$DEFAULT"`	
     to "$HOME/.Report.Spam"
    }
    if (/^Subject: BANNED/) 
    {
     `maildirmake -f Report.Banned "$DEFAULT"`	
     to "$HOME/.Report.Banned"
    }
    to "$HOME/.Report/"
}


if (/^X-Spam-Status: Yes.*/) 
{
#    log "Spam"
#    log "Spam $HOME $DEFAULT"
    `maildirmake -f SPAM "$DEFAULT"`	
    to "$HOME/.SPAM/"
}


include "$HOME/filter"

Note sur la derniere ligne :

Le fichier de filtre par utilisateur est forcement cree par l’api de gestion des utilisateurs.
