I'm not an expert, I just followed the same guide a few days ago
while preparing to front an old vpopmail system with postfix.  It
did work for me.

Before moving on to enabling the check in postfix, verify that the
dovecot side is working.

Your example test should work, I did the same here:

[root at util-b /usr/local/etc/postfix]# printf "recipient=chip at test.bway.net\nsize=12304\n\n" | nc mbox.i 25001
action=DUNNO

[root at util-b /usr/local/etc/postfix]# printf "recipient=chip at test.bway.net\nsize=123000000004\n\n" | nc mbox.i
25001 action=552 5.2.2 Mailbox is full

If that fails for you, examine the dovecot log.  In my case, I did
have to provide the full path to the "quota-status" binary and
dovecot complained about not being able to find it.  Make sure you
actually have quota-status installed.  Full dovecot snippet for this
below:

# report quota to postfix
# see http://sys4.de/en/blog/2013/04/08/postfix-dovecot-mailbox-quota/

plugin {
    quota_status_success = DUNNO
    quota_status_nouser = DUNNO
    quota_status_overquota = "552 5.2.2 Mailbox is full"
}

service quota-status {
    executable = /usr/local/libexec/dovecot/quota-status -p postfix
    inet_listener {
        address = 10.x.x.19  # In my case I want it listening on a particular IP
        port = 25001
    }
    client_limit = 5
}

If the dovecot portion is working, then move on to your postfix logs…
