The figure was a 42.9 percent drop from a year earlier and telecommunication officials said the fall came as a result of government and industry efforts to block junk messages.

The data collected from the Korea Communication Commission and the Korea Internet Security Agency also showed that Koreans received an average of 1.64 spam emails every day.
