dovecot - Mar 2019 - lua policy for Weakforce and web mail failed login attempts

The good news is I believe I got Weakforce running
1) curl -X GET http://127.0.0.1:8084/?command=ping -u wforce:ourpassword
{"status":"ok"}[

2) after running the sample for loop:
for a in {1..101};   do     curl -X POST -H "Content-Type:
application/json" --data '{"login":"ahu",
"remote": "127.0.0.1",
"pwhash":"1234'$a'",
"success":"false"}'
http://127.0.0.1:8084/?command=report -u wforce:ourpassword;   done

The result is:

{"status":"ok"}{"status":"ok"}{"status":"ok"}{

3) So checking the stats:

curl -X POST -H "Content-Type: application/json" --data
'{"ip":"127.0.0.1"}'
http://127.0.0.1:8084/?command=getDBStats -u
wforce:ourpassword

{"bl_expire": "", "bl_reason": "",
"blacklisted": false, "ip": "127.0.0.1",
"stats": {"OneHourDB": {"diffFailedPasswords":
93}}}

Notice the 93.

4) the reset works but I believe there's a bug in Getdbstats v2.0.0 where
"blacklisted" is always shown:
curl -X POST -H "Content-Type: application/json" --data
'{"ip":"127.0.0.1"}'
http://127.0.0.1:8084/?command=getDBStats -u
wforce:ourpassword

{"bl_expire": "", "bl_reason": "",
"blacklisted": false, "ip": "127.0.0.1",
"stats": {"OneHourDB": {"diffFailedPasswords":
0}}}[

5)
wforce -c
Read configuration from '/usr/local/etc/wforce.conf'
Connecting to 127.0.0.1:4004
> stats()
101 reports, 0 allow-queries (0 denies)

The 3 big questions I have:
a: how do I know IP's are being banned/rejected? Is there an alert creation
or a way to see in the logs that the rules are in affect?
b: since I installed via Git and ran "make" how to I get wforce
--daemon to
start on reboot? Is there a systemd file available?
c: How do I create a lua policy that would catch these web dovecot login
attempts?
