To help fight abuse and keep spam out of your inbox, Gmail uses email authentication to determine if a message actually originated from the address from which it appears to be sent.
Ili kusaidia kupigana na matumizi mabaya na kuzuia barua taka ndani ya kikasha chako, Gmail hutumia uthibitishaji wa barua pepe ili kuamua ikiwa kweli ujumbe ulitoka kwenye anwani ambayo inaonekana ilitumwa.
