postfix,openldap,cyrus working example

[Dirk Datzert <Dirk.Datzert@rasselstein-hoesch.de>]

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
myself.

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
receivers.

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
forwarders
forwardonly replaces all local receipients by forward-only mail address

Regards,
Dirk
