newfs options + hardware raid

Hi,

I've been looking at various archives of the FreeBSD lists, as well as
Google (web/usenet) and I'm not seeing anything about suggestions on
setting up a mail server with Maildir format boxes.  I posted to -isp, but
that seems pretty low-volume these days, so I thought I might find some
good advice here...

I've looked through some smaller mail servers that are using Maildir and
I'm finding the average message size is about 3K.  That leads me to
believe I'd likely be better off setting my blocksize down to perhaps 4096
or 8192 rather than the default 16K.  I may also bump the inodes up as I'm
looking at a total of about 4000 mailboxes, and eventually upwards of
8000, and I'd hate to dump/newfs/restore in the future...

My main question now is what I should do with the RAID setup.  I'll be
using an Adaptec 2100S and if I recall correctly there are block/stripe
size settings there as well.  This will be a 0+1 array.  Should I alter
those defaults to match the block size of the underlying filesystem??

Thanks, and sorry for the slightly OT,

Charles
