postfix,openldap,cyrus working example

Hi All,

I looked around in the different FAQ and mailing lists for my problem.
But I had to play with the LDAP_README and postfix configuration for

My goal was to get infos of mailgroups, mailforwarders and mailbox-infos
out of OpenLDAP, take it thru Postfix which does the expansion of
mailgroups and mailforwarders and take it to Cyrus for local mailbox

This scenario comes from a Netscape original Mail Server configuration
which should be migrated by OpenLDAP, Postfix and Cyrus IMAP.

I post this working solution for me and for all their out having the
same problem.

Basics of config:

Data in LDAP  (possible attributes)

uid: the final destination of local e-mail users
mail, mailalternateaddress: primary and secondary mail addresses
mailforwardingaddress: the mail-address to forward the origin to
maildeliveryoption: 'mailbox' - set if mail should delivered local to
cyrus - if not set than only forward
objectclass: 'person' - for a single mail address person
objectclass: 'mailGroup' - for a group of mail receipients
member, uniquemember: dn's members of the mailGroup

Data in main.cf (postfix config)

virtual_maps: ldap:mailgroups, ldap:mailboxes, ldap:forwardonly

mailgroups replaces the single mailgroup-address by every receipients
uid or mailforwardingaddress
mailboxes replaces all local receipients with local mailbox delivery or
forwardonly replaces all local receipients by forward-only mail address



# Insert text from sample-virtual.cf if you need virtual domain support.

mydomain: datzert.de

virtual_maps = ldap:mailgroups, ldap:mailboxes, ldap:forwardonly

mailgroups_server_host = localhost
mailgroups_search_base = o=datzert,c=de
mailgroups_query_filter =
mailgroups_result_attribute = uid,mailforwardingaddress
mailgroups_special_result_attribute = member,uniquemember
mailgroups_domain = $mydomain

mailboxes_server_host = localhost
mailboxes_search_base = o=datzert,c=de
mailboxes_query_filter =

mailboxes_result_attribute = uid,mailforwardingaddress
mailboxes_domain = $mydomain

forwardonly_server_host = localhost
forwardonly_search_base = o=datzert,c=de
forwardonly_query_filter =
forwardonly_result_attribute = mailforwardingaddress
forwardonly_domain = $mydomain

mailbox_transport = lmtp:unix:/var/imap/socket/lmtp

biff = no
