Inbound mail? You shouldn't lose outbound mail. Do you have a secondary (backup) MX? Or is this client pc's to server mail? > or that I am > having delays in outgoing mail.

Cacti (http://www.cacti.net/) It is pretty easy to setup, and maintain. Biggest issues would be the processor overhead when viewing graphs, and the web & SQL server requirement. Plus, set up snmp on any hosts/routers you want to monitor and you can monitor them from the one install. You can also use scripts to get data and graph it as well (e.g. mail queue lengths). Otherwise look up sa (sysstat package on Fedora - http://perso.wanadoo.fr/sebastien.godard/) which will record values for the local machine, but you would have to figure out how to graph the data yourself.
