Hi: I have a Postfix 2.3.3 running on CentOS 5.5 with a local installation of OpenLDAP. System users are mapped from my LDAP directory server according to /etc/nsswitch.conf and /etc/ldap.conf. I have LDAP groups what I use in postfix as a virtual alias maps like this:
virtual_alias_maps = ldap:/etc/postfix/groups.cf and the configuration of groups.cf queries my LDAP server like this: server_host = localhost search_base = ou=groups,dc=mydomain,dc=com query_filter = (&(cn=%u)(objectClass=posixGroup)) result_attribute = memberUid result_format = %s...@mydomain.com bind = no version = 3 I have users that belong to one or more LDAP groups and when people send e-mails to one of those users with Cc: to one of those groups (that contains one of those users), the final users receive multiplicated e-mails. How can I avoid this? I hope someone can help me. Thanks
