Try changing /etc/munin/plugin-conf.d/munin-node like: [postfix_mailstats] user root [postfix_mailvolume] group adm If mailstats works, but mailvolume still fails, then you know that either the adm group doesn\'t have rights to the necessary logfiles, or the group can\'t be set. Also be sure to set the path to the logfile using env.logfile in that same config file.
and or Make sure mail.log.1 (or whatever log file you\'re using) is not gziped by logrotate. ie:mail.log.1.gz is bad.
