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

[Charles Marcus]

Hi Timo,

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 
dovecot-uid* files

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 
accessing it?

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...
