These records help explain hosting, email, and domain delegation.&lt;/p&gt;&#10;&lt;h2 id="limits"&gt;Limits&lt;/h2&gt;&#10;&lt;p&gt;The presence of SPF, DKIM, or DMARC does not guarantee that a message is legitimate. Likewise, a domain with HTTPS and working DNS may still host fraud.&lt;/p&gt;</description></item><item><title>Have I Been Pwned</title><link>https://prossibrblog.pages.dev/en/tools/have-i-been-pwned/</link><pubDate>Sun, 08 Nov 2026 00:00:00 -0300</pubDate><guid>https://prossibrblog.pages.dev/en/tools/have-i-been-pwned/</guid><description>&lt;h2 id="what-an-incident-result-means"&gt;What an incident result means&lt;/h2&gt;&#10;&lt;p&gt;An address appearing in a known dataset indicates exposure associated with the reported incident.
