dovecot - Feb 2013 - statistics on proxy ???

Hi at all,
could I have imap statistics on my dovecot proxy server ??

Here my config:

# 2.1.13: /etc/dovecot/dovecot.conf
...
mail_plugins = stats
...
plugin {
   ...
   stats_refresh = 30 secs
   stats_track_cmds = yes
}
...
service stats {
   fifo_listener stats-mail {
     mode = 0666
   }
}
...
protocol imap {
   ...
   mail_plugins = stats imap_stats
}


File '/var/run/dovecot/stats' is always 0 byte:

# ls -la /var/run/dovecot/stats
srw-------. 1 root root 0 Feb 18 14:24 /var/run/dovecot/stats

and 'dovecotadm' say always:

# doveadm stats dump session
doveadm(root): Info: no statistics available


Is there something wrong in my config, or stats are not available on 
proxy ???

Cheers,
   Marco

Nope, sorry. Dovecot proxy is very dummy and can't provide any but the
most basic statistics, like number of connections, which you can get
another way.
