Google simplifies its SPF record and that is good news for everyone

At the start of December 2025, Google quietly made a meaningful change to the SPF record published at _spf.google.com. While the change may look subtle at first glance, it has clear benefits for anyone relying on Google in their own SPF configuration. A short history of Google’s

The new BIMI lps= tag, also known as the local-part selector, has been added to the BIMI specification. It allows domain owners to define different brand indicators based on the sender address (for example noreply@, support@, marketing@), without relying solely on the selector header.

With lps=, brands can assign unique BIMI logos to different sender types, exclude certain local-parts from showing any logo at all, and gain far more control over how their brand appears in recipients’ inboxes.

@cybertrapped Please note that DKIM validation requires the complete email, and even missing whitespace can cause the hash calculation of the body to fail. If you'd like full validation, simply send the email to learnDMARC.com and we'll handle it for you. If you're only interested in understanding the headers, use the "paste headers" feature instead.
@cybertrapped Pay attention to valid DKIM signatures. If a DKIM signature passes validation, the associated domain is—at minimum—partially responsible for the message.

@cybertrapped If you paste headers into LearnDMARC, we will visualize them for you, but do not check if they are valid. Please note that these headers may not be compliant with DMARC or SPF specifications. For example, when manually checking SPF for IP 192.184.11.189 on the domain abm.com, the result should be a permerror due to excessive void DNS lookups.

Received-SPF: permerror (abm.com ... _spf.salesforce.com: Maximum void DNS look-ups limit (2) exceeded) envelope-from="[email protected]"; client-ip=192.184.11.189
