Martin,

Today at the University of Florida, we began offering Roundcube for
one
of our major e-mail systems offered to students. We have around 60,000 IMAP users in an average week, and probably about a quarter of that number that visit our webmail during an average week.
We're hoping to contribute back to the project in terms of patches,
bug
reports, and feature requests. We're already amassing quite a body of usability feedback from our beta testing.
Welcome! We've been running RoundCube here at the University of Oregon for a little over a year. We continue to run it in parallel with a deprecated in-house webmail product, and have found that approximately 80% of our 65,000 users have happily made the migration on their own. Those that remain on the old product tend to be stodgy faculty or secretarial types that are resistant to change.
Besides some minor image replacement within the default skin to customize the logo and watermark, we've left the core code pretty much alone. We do have a few custom plugins to sync configuration and address book information with our other webmail, and have about a dozen of the community plugins enabled as well. I'm curious what patches or plugins you anticipate you'll need.
In terms of infrastructure, we have two dual-socket quad-core Xeons running RHEL5 behind a F5 hardware load balancer that is doing SSL offload. Each node runs a local instance of up-imapproxy, which in turn connects to a load-balanced pool of four Dovecot director proxies with 12 IMAP backend nodes behind them. We also have a MySQL master server (shared with other software) and local read-only slaves on the Roundcube nodes. Even under peak usage (~2k concurrent sessions) we run quite lightly loaded, but we like to overbuild by at least a factor of two so that we can withstand a single-site outage.
I'm curious to hear what your configuration and utilization look like!
