What constitutes "Invalid Format"

[Rob Tanner]

Hi,

I'm doing an upgrade from an earlier commercial version of cyrus server to 
the latest and greatest Cyrus 2.2.3 and seem to be plagued with mailboxes 
that generate the error "Mailbox has an invalid format".  Somewhere around a 
quarter of all the mailboxes are getting so flagged.  It is consistent in 
that if I clear out and then reload the spool partition or delete and rebuild 
mailboxes.db, the same mailboxes get flagged as having an invalid format.  It 
also appears arbitrary since I can find no significant differences between a 
mailbox so flagged and one that passes muster.

My question: What exactly are the criteria the software checks to determine 
if the mailbox format is valid or not?  I have gone through the source  in 
mailbox.c, where the error is generated, but that file is over 3,000 lines, 
and minimally self-documenting.  So if someone could tell me exactly what 
it's looking for when it generates the error, I would appreciate it.

Thanks,
Rob
