I'm using Dovecot at home, Cyrus at $WORK.  Both work very well for 
their respective environments.

Whatever you do, my experience between mailbox formats has been that 
mbox does not scale well and in fact can cause horrible problems when an 
individual folder gets too big.  Maildir seems to get around this 
effectively, but you would be wise to tune your filesystem inode size 
with your Maildir filesystem (as well as your mount options).
