Thanks for the quick response. Do you think it's more sensible to run cluebringer on each postfix box? My current design has two dedicated boxes for cluebringer. Is this overkill?

Active/Passive or Active/Active is fine by me. I was thinking about having two dedicated cluebringer servers connected to the same DB server and using something like keepalived and VRRP for a virtual IP that moves over to the second box in the event of failure. Will this be enough? I assume all the policies and quotas will be read from the database and everything will just carry on as normal. I'd guess if you have users processing millions of messages a day then this must be more than one server. Is there any options in Postfix to pool the servers? Something like: check_policy_service inet:10.10.10.1:10031 inet:10.10.10.2:10031 Then tweak the timeout to be low enough for it to retry the second server fairly quickly? cluebringer can be load balanced, either with multiple multi-master DB's running a cluebringer each, or the db's being load balanced with cluebringer running on each mailserver/clsuter If you have any problems while doing this, let me know ... the only issue we are aware of is a race condition on db insert when two records get inserted at the same time, I'd say one more report of this affecting a setup would push this to high priority and get it resolved within a few days rather than just looming around waiting for 'the correct' solution to pop up in my head :D -N
