Hello,
since mails sent to ldap groups must be expanded by the mta,
I tried to come up with a working configuration.
It works (almost), the problem I actually see, is that postfix expands
the recipients to all members, BUT then also adds the email address of
the group to the list.
In this case grup...@aarboard.ch
Here the group expanding in postfix:
server_host = 192.168.202.11
search_base = ou=aarboard.ch,ou=groups,o=mailhosting2,dc=aarboard,dc=ch
query_filter = (&(mail=%s)(objectclass=groupOfUniqueNames))
result_attribute = mail
special_result_attribute = uniquemember
And the associated ldap entries:
LDAP Group:
dn: cn=Gruppe1,ou=aarboard.ch,ou=groups,o=mailhosting2,dc=aarboard,dc=ch
objectClass: extensibleObject
objectClass: top
objectClass: groupOfUniqueNames
cn: Gruppe1
uniqueMember: mail=a.sch...@aarboard.ch,jvd=aarboard.ch,o=mailhosting2,dc=aa
rboard,dc=ch
uniqueMember: mail=a.schi...@aarboard.ch,jvd=aarboard.ch,o=mailhosting2,dc=a
arboard,dc=ch
mail:grup...@aarboard.ch
And the LDAP - Mailusers
dn: mail=a.schi...@aarboard.ch,jvd=aarboard.ch,o=mailhosting2,dc=aarboard,dc
=ch
objectClass: JammMailAccount
objectClass: top
accountActive: TRUE
delete: FALSE
homeDirectory: /home/vmail/domains
lastChange: 1366702070
mail: a.schi...@aarboard.ch
mailbox: aarboard.ch/a.schild2/
and
dn: mail=a.sch...@aarboard.ch,jvd=aarboard.ch,o=mailhosting2,dc=aarboard,dc=
ch
objectClass: JammMailAccount
objectClass: top
accountActive: TRUE
delete: FALSE
homeDirectory: /home/vmail/domains
lastChange: 1304579374
mail: a.sch...@aarboard.ch
mailbox: aarboard.ch/a.schild/
Already the postmap command shows the wrong number of results:
postmap -v -q grup...@aarboard.ch ldap:/etc/postfix/expand_groups.cf
returns:
postmap: dict_ldap_lookup: In dict_ldap_lookup
postmap: dict_ldap_lookup: No existing connection for LDAP source

a.sch...@aarboard.ch,a.schi...@aarboard.ch,grup...@aarboard.ch
a.sch...@aarboard.ch,a.schi...@aarboard.ch,grup...@aarboard.ch
Any ideas what might be wrong or how I can remove the group-email from
the group itself?
With best regards
