+#           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.
+#

+# 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
