We would like to whitelist the following IP subnet.
I've added the entry into the whitelist, but mails from an IP within this subnet is still being blocked.
Am I doing something wrong in here? See attached printscreen.
Thanks in advance,
The mail doesn't accept CIDR notation, but it accepts partial IP addresses to whitelist a network. So, the range below should be replaced by xxx.xx. with final dot.
It will whitelist more than the /17 CIDR, but if it works as expected, it can be refined later.
