I stumbled over Amedee Van Gasse’s munin plugin to monitor the size of a Maildir for a selected set of users, and I’m linking to it because the idea amused me. (Don’t worry about the Dutch language: the script is in English. :-) ) Should be a snap to convert this to use with collectd or any other system you use. Get it here.
