Hi,

we are providing Mail-Service (POP3, IMAP; either TLS or SSL) to 22000 
students here at my university.

There are 2 machines running as active-passive cluster with DRBD to sync 
the maildata. Each box is a 4 core Intel(R) Xeon(R) CPU 5160 @ 3.00GHz 
with 8 gigs RAM.

After a tuneup for DRBD and upgrade to dovecot 1.1 average load is 
around 1.0.

HTH
