Is there an even better > configuration than what I'm doing? What we have is 2 identical servers running Postfix, MySQL and Policyd. Each server uses it's local MySQL and Policyd. We turned on MySQL Dual Master Replication (please read up on the subject if you're going to do things like that) for the Policyd database so that both servers share the same Policyd information. If one server goes down, the other can take over instantly with the same information. Both servers are in use so if a server would go down, one server would get the load of the other too, but we have sufficient hardware specs to take that hit. There is a catch when one server really does go down: MySQL replication doesn't work anymore. You'll have to get the databases in sync again and that can be a pain if you don't know how. I have not yet experienced any problems using this setup. If anyone does, please let me (us) know. -- Rob ------------------------------------------------------------------------- Take Surveys.
