[exim] Limit on number of blacklists used ?

Hi All

Has anyone any idea why the following doesn't work ? It uses a number of public blacklists and 2 zones on a private one (actual private domain names below are changed to ip.bl.domain.example and ip2.bl.domain.example). The problem is that it refuses to lookup on the second of the private lists. The lookups just aren't happening. In the real exim.conf file, the names are correct - no typos.

Is there a limit to the number of rbl's that can be used ?

Also, are all lists looked up on at the same time or are they processed in order please ?

I have been reading the documentation but cannot find any reference to either question, one way or the other.

Many thanks

Phil
