Dovecot quota and Postfix smtpd_recipient_restrictions?

I configured it before the "permit_sasl_authenticated" and the "reject" statement.

According to: http://www.postfix.org/SMTPD_POLICY_README.html try on your postfix:

telnet mailstore.example.com 12340

and insert the following lines:

sender=somesender at somedomain.com
recipient=your at recipient.com
size=12345
[empty line]


Set a size= in bytes which is greater that your configured quota.
In theory the policy service should respond with your configured error message "552 5.2.2 Mailbox is full".

Example on my server:

...
sender=postmaster at somedomain.com
recipient=my at recipient.com
size=123450000000

action=552 5.2.2 Mailbox is full
...


For a livetest reduce the quota of your testaccount to ex. 100KB and the send a mail > 100BK from outside to it. You should see the "552" error 
message in your logs and you should get back a bouncemail from the sending server.

Hope I explained it correct.

Best
