Moving from cIMAP-2.3.16 to 3.0.5

[Nic Bernstein]

James,
Patrick is entirely correct.  As explained in the man page for 
ctl_mboxlist(8) the "-f" flag is to specify an alternative input file 
(mailbox database) not an output file.  Output is via standard out, and 
can redirected into the file of your choice, or piped to the new host, 
like so:

    $ sudo -u cyrus /usr/lib/cyrus-imapd/ctl_mboxlist -d | ssh -tt newhost.example.com sudo ctl_mboxlist -u

Assuming you have the configuration directory specified in imapd.conf(5) 
on both systems, the right DB files should be used.

Cheers,
     -nic
