[Dovecot] Zero-sized Maildir files and index corruption on over-quota

Yes.

I do read the list.

As I recall, this is about index corruption. What we face is not index corruption, but zero-length data files. Of course, for dovecot's program logic, this is an index corruption in the sense that the length recorded in the index (which is in fact correct) doesn't match the file size (because the file has been truncated to zero length).

Yes, thanks, I already read that when it came up on the list.
