dovecot - Feb 2011 - FreeBSD tuning for a dovecot + postfix server ?

Hello

I've googled around  to tune a bit my mailhub ( AMD64 FreeBSD 8.1, 12 Gb 
RAM, 2 Tb raid5 disks , ~4000 mailboxes unix users )
but I am a bit confused,

All my clients use thunderbird as MUA ( IMAP, IMAPS ) to connect to the 
mailhub
no direct access to the machine.

Any of you guys has some pointer to give ?
thanks a lot

I guess you mean 12 Go (or 12 GB) ;-p

the answer is: when tuning is needed, you will know it: you will have
concrete problems.

if you observe no problem, tune your week-end instead. as the saying
goes: "premature optimisation is the root of all evil".
