Attackers may use the name of an executive, supplier or known company to make a message look legitimate.<\/p>\n<h2>Display name and actual address may differ<\/h2>\n<p>A message can show a familiar display name while the underlying sender address belongs to an unrelated domain.<\/p>\n<h2>What is domain spoofing?<\/h2>\n<p>Some attacks attempt to imitate not only a person&#8217;s name but also the company&#8217;s domain identity, which is why domain authentication is important.<\/p>\n<h2>How do SPF, DKIM and DMARC help?<\/h2>\n<p>These mechanisms help receiving systems evaluate whether a message originated from an authorized source.
