I create the list in ldap with groups. in my main.cf: alias_maps = hash:/etc/aliases, ldap:/etc/postfix/ldap.cf
ldap.cf contains: server_host = server.ldap search_base = ou=Groups,dc=domain,dc=my result_attribute = memberUid scope = sub query_filter = mail=%s when you create group, must put attributes: maildrop and mail maildrop: gr...@mydomain.com mail: group after must add the users belong this group. I dont edit never /etc/aliases because my users are OpenLdap. Ralf Hildebrandt said, is valid also. -- Jose Alberto Pertuz GNU-Linux user #452473 Caracas,Venezuela 58+414+1279657
