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
