Some Postfix nuts have said that you can somehow make the backup MX aware of all the users, but I don't know how or if the qmail patch supports anything like this, and I've also heard that it can be done with LDAP, but having never set up LDAP, that seems overly complex, and sounds like it would rely on some LDAP server being up which would defeat the purpose (our backup MX is at a geographically distant location, and is intended to be able to run fine in the event of all our other machines going down). Ideas? Further knowledge?
