dovecot - Sep 2015 - doveadm quota recalc problem for domain

Hello,

I've set up user quota and domain quota for dict SQL and all seems OK.

New mail for user increase the user quota and the domain quota.

Deleting email count down user quota and domain quota.

But in case of SQL failure, I'm trying to rebuild the user quota and 
domain quota with doveadm quota recalc.

The problem is that the command :

'doveadm quota recalc -u foo at bar' sets the domain quota only with
user
foo at bar

even when I try a domain quota recalc :

doveadm quota recalc -A

or

doveadm quota recalc -u *@bar (only one user is taken in account for the 
domain quota and not all the user).

The domain SQL database is broken with value of only one user for the 
whole domain quota.

So how to achieve rebuild domain quota correctly with doveadm ?

Thanks a lot.

Samuel.
