SRX

I would like to have my SRX345 Pull an IP List to ban to access to my mail server for people that attempt to hack my mail accounts. I already have a solution that bans them locally and generates an IP Ban list on a web page. 

I have a web server that has a real time plain_text page that generates all the IPs to block. When I used the config I found on another side it took it but nothing happens and am notsure if it is working at all. In Jweb I do not see what I have added to the config.  Do I have to do anything to tell what Policy and what servers to ban these IP from accessing??
Is there a place in Jweb I can see my feed???

Below is what I have added to my config

security {
dynamic-address {
feed-server localwebserver {
hostname 10.10.20.105;
update-interval 3600;
hold-interval 86400;
feed-name web-blacklist {
path /api/blacklist_plain_text;
}
}
address-name address-blacklist {
profile {
feed-name web-blacklist;
}
}
}
