[Dovecot] Dovecot Quota plugin as Couier quota

[Antonio Perez-Aranda]

I don't like that, because \Deleted files are in disk and take space.

But well, it's a customer decissión.

Another posibility could be delete-to-trash but it doesn't run on Dovecot 2.0.x.

I though that lazy-expunge take \Deleted files and "expunged" files, but not.

I think that I can use this with the ":" modification until
delete-to-trash run on Dovecot 2.0
