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?
The start of subnet 194.149.65.0/23 is 194.149.64.0. 194.149.64.0/23
encompasses 194.149.64.0 through 194.149.65.255. You want
194.149.65.0/24 and 194.149.66.0/24. Essentially, you've joined the
second /24 of a /23 network with the first /24 of the next /23 network.
You can't do that.
