Where be these elusive imapd.conf docs?  I just read through the 
imapd.conf man page and couldn't find anything about this.

I have:
pgoetz at www:~$ ls /usr/sbin/ctl*
/usr/sbin/ctl_cyrusdb  /usr/sbin/ctl_deliver  /usr/sbin/ctl_mboxlist

It doesn't look like any of these dump a database except perhaps

    ctl_cyrusdb -c

And it's not at all clear what settings would be changed if the database 
is dumped ... to a plain text file?  CSV?  No mention of this on the 
ctl_cyrsudb man page (or where the database is archived, for that matter).
