Is it possible to specify the blackhole servers in a separate file? I only found the option, that you specify reject_rbl_client in the main.cf multiple times. My problem is that i have a cluster of postfix servers and settings like transport map and relay domains are all in a seperate file which can be easily file synced, so that i do not need to make the changes to every sever, just once. However with reject_rbl_client it seems i would have to modify the main.cf on each machine, since i cannot sync this file, it contains server specific values.
Any idea if it is possible to use map or pointers to a file for this config?
