[Dovecot] mailbox lock

[Thiago Monaco Papageorgiou]

Ok, but we must lock the mailbox because we often move groups of mailbox 
from a file system to another. While the mailboxes are being moved, our 
LDA shouldn't delivery a new message at the old mailbox, and isn't able 
to delivery at the new one. The mailbox is unlocked after the exchange 
of the file system , if the dovecot locks the index files and then the 
mailbox exchanges of file system, what will unlock the index files of 
the dovecot?
The dovecot process that perform the lock, will unlock the old index 
files. This old index files will be erased as well as the whole old 
mailbox, the new mailbox, that was moved to an another file system, will 
remains locked.

We have almost 10M of mailboxes, if the chance that it happens is 
something like 1/1M, it will happens 10 times per day!
