Hi,
I would like to enable (the same) quota (count) for all (virtual)users, on Debian Stretch, Postfix 3.1.8, Dovecot 2.2.27, and is not clear for me if I need to tell Postfix to communicate with the service in /etc/postfix/main.cf as here:smtpd_recipient_restrictions = ... check_policy_service inet:mailstore.example.com:12340
I configured it like your example above and it works for me. Best Urban
