journaling fs and large mailbox format

[Z.C.B.]

From personal experience on a smaller system(~1000 accounts and
nearly all ways less than 45MB boxes) I would suggest avoiding mboxes
all together. Maildir is all ways the way to go. For cleaning stuff
out automatically and ect, maildir is much nicer as well.

Also is this vnodes or inodes? See the tuning man pages. For vnodes,
there are some sysctls.
