[Dovecot] Tools to analyze status/stats?

[Peter Fern]

The majority of those stats are most easily pulled from your MTA, and if 
you're using one of the popular ones there are bound to be numerous 
tools that will do this for you... eg - if you use postfix (or others) 
you might look at:  http://www.postfix.org/addon.html#logfile
