The error message seems reasonably clear. You shouldn't have any non-zero bits after the bit position indicated by the network size (/23 below). I.e. those CIDR entries are inconsistent with CIDR notation. Hi Mark, thanks for your response, and I apologize if my brain is not grasping what your saying. If I am blocking 194.149.65.0/23 this is a standard format, it tells us that the IP's are the 194.149.65.0-255 and 194.149.66.0-255. Are we saying that the CIDR rule within postfix only wants 1 class C at a time?
