#  2006.aug.21. - grin@grin.hu - fix autoconf, insecure tmp file
#               - added mail count
#               - save less irrelevant data into tmp
#               - requires in plugin-conf.d/munin-node (to access syslog):
#                 [spamassassin]
#                 group adm
#
# Magic markers - optional - used by installation scripts and
# munin-config:
#
#%# family=manual
#%# capabilities=autoconf
