[exim] dnslists mysql lookup

Hi,

I'm having a bit of a thing... Should be relatively simple I think...

deny dnslists = ${lookup mysql{SELECT RBLList FROM RBLTable WHERE Domain =
'$domain'}}

The above, a extensively simplified query.

Now, the query returns a list of RBL Hosts that I want exim to check
against. However, running via a debug, exim only checks the first record
returned by MySQL, and not against all the records....

How can I get exim to run through all the RBL hosts returned by the SQL?

Thanks,
Chris.
