Try a subroutine something like this (entirely untested):
check_rbls:
# Split first RBL off into acl_m2
warn set acl_m2 = ${sg {$acl_m1}{^([^:]*)}{\$1}}
# Remove it from the list
warn set acl_m1 = ${sg {$acl_m1}{^[^:]*:*}{}}
warn dnslists = $acl_m2
set acl_m0 = ${eval:$acl_m0+1}
message = X-RBL-Warning: $dnslist_domain: $dnslist_text
# Break out of loop if there are no RBLs left in $acl_m1
accept condition = ${if eq {$acl_m1}{} {no}{yes}}
accept acl = check_rbls
.... invoked like this...
warn set acl_m1 = $address_data
warn acl = check_rbls
