Because it's not ARIN IP space?

KRNIC is not an ISP but a National Internet Registry similar to APNIC.
The followings is organization information that is using the IPv4 address.

IPv4 Address       : 125.187.32.0-125.187.47.255
Network Name       : POWC-503
Connect ISP Name   : Xpeed
Registration Date  : 20051128
Publishes          : Y

Whether or not you should accept email from Korean end-user IP space is 
left as exercise for the reader.
