no urgent need for stats
i count pop3 logins with xymon out of syslog in realtime, also logwatch
reports lmtp/pop3/imap daily for each user by cron in daily terms

perhaps have a look at

http://sys4.de/de/blog/2013/01/10/xymon-dovecot-count-imap-pop3-logins-graph-central-rsyslog-server-ubuntu-lucid/

if you have xymon monitoring etc installed you have other stuff like cpu
, mem, disk io too

i ll plan to write some solution for xymon retrieve data out of dovecot
stats too
