Just curious… thought there used to be a limit (not sure if hard, theoretical, etc…) to the # of mail replicas allowed in the clbdir. ~8K or so. I’m hoping this is no longer the case. We have 15K ~dormant/legacy accounts that must be retained. The current use is no more than ~10%. The servers are obviously capable of handle 1000s of concurrent sessions vs. the daily average of 800-1200 users. I know… why clustering. Long story… just must have it (beyond me). Back to the ?.. assuming this can be done, right? Don’t want to run into any barriers…
