 ## mbox-specific settings

 # Which locking methods to use for locking mbox. There are four available:
 #  dotlock: Create <mailbox>.lock file. This is the oldest and most NFS-safe
 #           solution. If you want to use /var/mail/ like directory, the users
 #           will need write access to that directory.
 #  dotlock_try: Same as dotlock, but if it fails because of permissions or
 #               because there isn't enough disk space, just skip it.
 #  fcntl  : Use this if possible. Works with NFS too if lockd is used.
 #  flock  : May not exist in all systems. Doesn't work with NFS.
 #  lockf  : May not exist in all systems. Doesn't work with NFS.
 #
 # You can use multiple locking methods; if you do the order they're declared
 # in is important to avoid deadlocks if other MTAs/MUAs are using multiple
 # locking methods as well. Some operating systems don't allow using some of
 # them simultaneously.
 #
 # The Debian value for mbox_write_locks differs from upstream Dovecot. It is
 # changed to be compliant with Debian Policy (section 11.6) for NFS safety.

 # When mbox changes unexpectedly we have to fully read it to find out what
 # changed. If the mbox is large this can take a long time. Since the change
 # is usually just a newly appended mail, it'd be faster to simply read the
 # new mails. If this setting is enabled, Dovecot does this but still safely
 # fallbacks to re-reading the whole mbox file whenever something in mbox isn't
 # how it's expected to be. The only real downside to this setting is that if
 # some other MUA changes message flags, Dovecot doesn't notice it immediately.
 # Note that a full sync is done with SELECT, EXAMINE, EXPUNGE and CHECK 
 # commands.
