[Exim] rbl plus in exim 4.20

I am new to exim, trying to use rbl-plus in exim 4.20
I have the following entries in the alc part of the configuration file.

deny message = rejected because $send_host_address is in the black
list at $dnslist_domain
dnslist = rbl-plus.mail-abuse.ja.net

Do I need any other entries and how do I test this ?

Thank you
Ravi
