It's like standart clustering. See http://www.lifewithqmail.org/ldap for examples.
Important files are: - mailHost Attribute (name or ip of north/east/south...) - set ~control/me or ~control/ldapclusterhosts hostname according to mailHost. It is important that your dns, ~control/me, ~control/ldapclusterhosts and mailHost are in sync. Then you need to setup qmail-qmqpd on all 5 servers and that's it. qmail-ldap's clustering mechanism is not limited to location. Befor you run your system in production try out what happens if one machine is not reachable (I'm not 100% sure what happens (I think it will bounce after a while)). -- :wq Claudio tail -23 QLDAPINSTALL
