I am running 2.0.5 (svn repository) in production for about a thousand users without major issues.

Please Sir, on what OS and architecture ?

I think the stability has less to do with that, and more to do with what parts of Dovecot you want to use. If your test setup works fine with the most common clients you use, and it survives a bit of stress testing, it should work fine.

The things I still mostly worry about are some rare errors/crashes.
