Kudos on a fantastic project - having had experience setting up a full email server before Mail-In-a-Box seriously takes away headaches.
I would like to setup some sort of monitoring for my server (I have about 15 family members now using my server and I want to be proactive in keeping it up) something along the lines of munin, nagios, zabbix, etc.
Any suggestions or thoughts on which might be easier to setup with Mail-in-a-Box given the custom configuration of nginx?
