backupd and sync_client Syntax error

[Marco]

Ouch, sorry, ignore this.

I suppose to have found the problem.

My goal is to sync from Cyrus IMAP 2.4 to 3.2, and to 3.2 to a backupd host.
I see it works just starting by hand the sync_client in Cyrus IMAP 2.4, 
meanwhile in the middle host the rolling mode is sufficient with 
sync_log_chain.

But I had a bad Cyrus IMAP 2.4 with some mailboxes which had references 
in mailboxes.db only, and not in file system and metadata.

Solving above error, then sync_client from 3.2 IMAP host to backupd host 
works.

I don't know why I don't see errors in sync_client from 2.4 to 3.2 already.

Cheers
Marco
