I ran into a similar problem when trying to block people from sending
messages of a specific size and to tell them the size.
Something like this for you:
warn message = X-RBL-hit-at: $acl_m9;
set acl_m9 = ${lookup{$sender_host_address}cdb{GRULESD/cdb.rblhosts.cdb}{$value}fail}
condition = ${if eq{$acl_m9}{}{no}{yes}}
You shouldn't need the condition, but I put it there anyway. If the lookup
didn't find anything, it fails, which skips this acl.
If it works/doesn't work, I'd like to know.
