Yes I heard of 4.4BSD soft updates....

With all the respect, I just experienced it some time ago. And it does
creates lots of troubles, unless the filesystem is tuned for handling
the Maildirs. (less then 1000 accounts with "Leave messages on server
unless 7 days old" in Outlook did the job)

This means estimating the average size of the Maildir/ files, estimating
the total number of Maildirs (which is easier), and applying some math.

I received a link which thoroughly explains the steps here:
