dovecot - Apr 2010 - corrupted index cache file, physcial size, in migration to snow leopard

Hi,

I am in the middle of migrating a server from Apple's leopard to snow  
leopard.  Having big problems with migrating mail to dovecot.  The  
version is:

# dovecotd --version
1.1.17apple0.5

and I use the migration script provide by Apple,

/usr/libexec/dovecot/migrate_mail_data.pl

The current problems concern migrating imap accounts.

The old data typically shows up to mail clients as only partially  
migrated, with some issues there, like folders change from being  
listed on the server to being listed locally, but the biggest problem  
is that many many messages and folders have disappeared from view.

But on the server, they seem to be there, in their correctly migrated  
place.

The log files are full of messages like the ones below, which I'm  
guessing has something to do with the problem.  The number of files  
with this problem is huge.

Are there any scripts to rebuild the index cache files with correct  
physical sizes?

Thanks in advance for any help!

Best,
	Norman
