If the file size exceeds 5120 bytes it will be recreated.  maildrop had
some logic such as if the file is over 2 hours old recreate it (or
something like that).  Most importantly though, Dovecot knows the quota
value from your DB because it got that in the auth query, and if Dovecot
sees a different quota value in maildirsize that what the DB reported,
Dovecot will recreate the maildirsize file - because at that point the
maildirsize file is known to be wrong.  So your quota changes should take
effect immediately.

The only missing piece to the puzzle is handling the case where the
maildirsize file doesn't exist when GETQUOTAROOT is called.
