Reconstructing Mailboxes - HELP!

[Robert Scussel]

Just run :

	sudo -u cyrus /usr/cyrus/bin/ctl_mboxlist -d > filename

and then after you have moved the old one out of the way (import over 
the old doesn't/didn't work well) then just do:

	sudo -u cyrus /usr/cyrus/bin/ctl_mboxlist -u < filename

Before you start, let me clarify:

   remove the files in /var/spool/imapdb/db -- and always do an rsync of 
/var/spool/imapdb to somewhere before starting in case things go 
horribly wrong.
