The goal here is to monitor servers running Postfix to determine the number of email messages delivered locally and abroad and to graph that data. The data will be made available via Net-SNMP for collection using your NMS of choice. Postfix homepage: http://www.postfix.org/ Basis for this Work The methods outlined below are based on the work of Craig Sanders http://taz.net.au/postfix/mrtg/. Some things that are done different here: Only one database file is used for storing the data instead of two.
