there are problems with quota dict when multiple dovecot deliver processes are 
launched in parallel. It can be reproduced by sending a mail with multiple 
different recipients - the mail is delivered OK to all recipients, but the 
quota are not updated correctly in sql. I looked at the code and it seems 
that the problem is somewhere in dict cache.
If I configure in Postfix max number of deliver processes to 1, dict quota is 
updated correctly.

postconf -n output:
