====== Postfix Statistics with Zabbix ======
This is a nice way to take postfix mail stats and input them into Zabbix.


There are a few shortcomings to this method as for data representation, but it is still a very efficient way to get the data into zabbix on busy mail servers.
===== Needed programs: =====

  * pflogsumm (http://jimsun.linxnet.com/postfix_contrib.html)
  * logtail (http://packages.debian.org/stable/admin/logtail)
  * zabbix-sender

===== Install steps: =====

  - Install pflogsumm and logtail on the host you want to monitor
  - Create items in zabbix for pfreceived, etc etc (as you see in the bash script below). Remember we are using zabbix_sender so the items have to be of type "ZABBIX trapper"
  - Save the bash script onto the host you want to monitor and modify the script where necessary
  - Create a crontab line as described below
  - Update zabbix_agentd.conf per below and create associated item as active check.
  - importer le template dans zabbix {{:linux:zabbix:zbx_postfix_template.xml|}}


===== CODE =====
