# maildir handler, as part of a backupninja run.
#
# The maildir handler slowly creates a backup of each user's
# maildir to a remote server. It is designed to be run with
# low overhead in terms of CPU and bandwidth, so it runs pretty
# slow. Hardlinking is used to save storage space. The actual
# maildir is stored within each snapshot directory.
#
# Valid attributes for this type are:
#
#   order: The prefix to give to the handler config filename, to set
#      order in which the actions are executed during the backup run.
#
#   ensure: Allows you to delete an entry if you don't want it any more
#      (but be sure to keep the configdir, name, and order the same, so
#      that we can find the correct file to remove).
