[Dovecot] Statistics

[Pierre]

HI list,
According to this:
http://webcache.googleusercontent.com/search?q=cache:QMGLz9SVNdwJ:www.dovecot.org/talks/berlin-2009-07-02.ppt+dovecot+heavy+users+stats&cd=1&hl=fr&ct=clnk&client=iceweasel-a
<<
# Use statistics to automatically distribute heavy users to different servers
    * v1.2 can export very detailed statistics via plugin
>>

I can't find this "detailed statistics" plugin, I only found this:
http://www.dovecot.org/patches/2.0/stats-plugin.c

But it only seems to add a "stats" IMAP command.

Please can somebody confirm or give me a link to this plugin ?
I really need to identify "heavy" users,so this plugin may be really usefull for me.


Thanks a lot,
Pierre
