+
+postfix_stats - Munin plugin to monitor postfix statistics.
+
+=head1 APPLICABLE SYSTEMS
+
+Any system where pflogsumm script can be executed.

+There is no default configuration. This is an example config for Ubuntu:
+
+  [postfix_stats]
+   env.logfiles /var/log/syslog /var/log/syslog.1
+   env.pflogsumm pflogsumm
+
+env.logfiles contains space separated syslog logfiles, usually current log
+and previous log. You can add more log files if you want, but this may 
+increase the time required for analysis.
+
+env.pflogsumm The "pflogsumm" script, can be pflogsumm.pl if it was manually
+downloaded and installed, or "pflogsumm" if it was installed by a package 
+manager (like apt-get).
+
