Getting error "Mailbox has an invalid format"

[Rob Tanner]

Hi,

I'm trying to upgrade from an old ESYS (commercial version of cyrus) to 
cyrus-imap 2.2.3.  I build the mailboxes db from the ESYS flat mailboxes file 
according to the directions:

STEP 1:   ctl_mboxlist -u < mailboxes
STEP 2:   ctl_cyrusdb -c

In ther mailboxes themselves, I added an empty cyrus.header file and eleted 
the old ESYS fdb.* files.  When I do a reconstruct -r user.<mailbox> for 
anyone user, somewhere between a quarter to a half of the mailboxes fail to 
reconstruct with the error "Mailbox has an invalid format".  On the LINUX 
side, permissions and even the extended attributes are the same.  Everything 
is owned by cyrus:mail, and there's no obvious difference in the mailbox db 
data.  I've alos rebuilt everything and the results are the same.

What exactly are the things that the software checks to decide that the 
mailbox has an invalid format?  I've exhausted my ideas.

Thanks,
Rob
