Thanks for the info. I conclude that it is no problem to serve about 1000 concurrent users per server (with dovecot 1.1 probably even lots more!). Unfortunately I cannot compare this with our setup as we do not have dedicated NFS-boxes (Netapp). Our servers have to do local hard disk IO as well. I think this probably decreases performance (?).
