# PROVIDE: fetchmail
# REQUIRE: LOGIN mail
# KEYWORD: shutdown

#
# Add the following lines to /etc/rc.conf to fetchmail in daemon
# mode.
#
# fetchmail_enable="YES"
#
# There are two variants:
#
#  * Single system-wide fetchmail daemon:
#    - It is run as user `fetchmail_user' (default: fetchmail)
#      Note: The directory /var/run/fetchmail must be writable for
#            'fetchmail_user'.
#    - All configuration is contained in one global file
#      'fetchmail_config' (default: %%PREFIX%%/etc/fetchmailrc)
#      that must be owned by 'fetchmail_user' (mode 700)
#    - The fetchmail daemon awakes to fetch mail every 
#      'fetchmail_polling_interval' seconds (default: 900).
#
#  * Per-user daemon
#    - Users for which a fetchmail daemon is to be started must be
#      listed in 'fetchmail_users', e.g. fetchmail_users="user1 user2"
#      The 'fetchmail_user' (sic!) variable is ignored in this
#      configuration variant.
#    - The config files for the individual users must be located at
#      ${fetchmail_home_prefix}/${user}/${fetchmail_config_name}. The
#      default for 'fetchmail_home_prefix' is "/home", and that for
#      'fetchmail_config_name' is ".fetchmailrc".
#    - Note that "${fetchmail_home_prefix}/${user}" must be writable
#      for ${user} since it is used to store the per-user PID files!
#    - There are user-specific versions of 'fetchmail_config' and
#      'fetchmail_polling_interval' that can be used to override the
#      defaults, i.e. for the user 'user1' there are variables
#      'fetchmail_user1_config' and 'fetchmail_user1_polling_interval'
#    - All commands (e.g. start, stop, awaken (see below)) can be either
#      passed to all instances of the daemon (if %%PREFIX%%/etc/rc.d/fetchmail)
#      is run as root), or just to the instance belonging to the respective
#      user.
#
# Extra commands:
#
#  * 'awaken': Sends a signal to the daemon(s) to check for new mail
#     immediately
#
# Fetchmail configuration:
#
# In any case, you will need a working fetchmailrc file. Please consult
# the man page fetchmail(1), the documentation in %%PREFIX%%/share/doc/fetchmail/
# and/or the material found at <http://www.fetchmail.info/>.
