[Dovecot] director in large(ish) environments

[Cor Bosman]

Hey all, just wondering who here is running the director service in a larger environment. I just switched our whole production setup to the director and am quite pleased with the result. We're doing a peak of about 25000 tot 30000 concurrent sessions on 3 servers. But ive shut 1 server down a couple of days ago to see what would happen and 2 servers carried the load easily. (16 CPU, 24GB memory servers).   If others are using the director on larger setups maybe we can all post when things do or dont work well. 

Now to see if the solution is better than the problem :)
