After upgrading to 1.5.0 postfix stopped accepting new mail, checking the postfix.log it was complaining about not being able to connect to localhost:12340, the Dovecot Quota port.

I noticed in the /etc/dovecot/dovecot.conf file no longer contains:

service quota-status {
    # '-p <protocol>'. Currently only 'postfix' protocol is supported.
    executable = quota-status -p postfix
    client_limit = 1000
    inet_listener {
        address = 127.0.0.1
        port = 12340
    }
}

I don't remember seeing any reference to this change in the release notes so not exactly sure how it happened. I used the saved config file and brought things back up and mail started flowing again.
