Bold claim given the mail never reached "the wrong kind of native" during either the Mau Mau rebellion / Mau Mau uprising / Kenya Emergency (1952–1960) or the Malayan Emergency / Anti–British National Liberation War (1948–1960).
To be honest, mail rarely reached the natives, right or wrong, outside of the hot times that saw thousands killed.
Just a general note that things didn't generally run well in the colonies for natives under British rule.
I'll concede they ran well enough for a privileged few who were closely aligned with the British .. but that was not a representative slice of the whole.
