[Dovecot] Thunderbird message cache out of sync after repetitive rsyncs...

Thanks for the reply, but I think I figured it out...
I just realized...
1. the source does NOT have any index files at all, only the
2. the target (the account I am testing with) *does* have *two* index
files (but not the main dovecot.index file), because they are created
when I access the account
So, maybe I just need to delete the index files on the target before
I also really, really need to know why I don't have the main
dovecot.index file... ???
I'll test the above hypothesis after the current backup finishes...
