Which RBL Filter blocks the IP-Address?

How can i find out, which RBL Filter is blocking a specific IP address?

After a RBL blocked an ip address, the ip will be listet for 7 days in the list of blocked IP Addresses (Webinterface -> Configuration -> E-Mail Transport -> Network Restrictions -> Blacklist).
A search can be performed for the IP Address in the list.
The "valid to" column can be used to determine the time when the IP was blacklisted.
Now the Reddoxx Applinace Log (Webinterface -> Administration -> log files) can be used to search for the blacklist ip, there you see which RBL classfied the IP as Spam.
