Google has streamlined its SPF record, reducing it by three DNS lookups. uriports.com/blog/google-sim…

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@). uriports.com/blog/bimi-lps-t…

Google DMARC reports are back! After going quiet since April 13, Google has resumed sending DMARC aggregate reports as of 19:15 UTC today.

Chrome now supports potential-permissions-policy-violation Reports! With the 134 update, Chrome can now generate potential-permissions-policy-violation reports, helping developers catch Permissions Policy conflicts before they happen. uriports.com/blog/potential-…
Out of the top million domains, just 303 have implemented a Web Key Directory (WKD) for publishing OpenPGP keys. If you publish PGP keys via WKD and want to verify your setup, or want to start using WKD, you can use our new, free service at WebKeyDirectory.com.
We made something cool today. A tool to help you verify your Web Key Directory (WKD) configuration. For anyone using #OpenPGP, #WKD makes your key discoverable using only your email address by placing a binary key in the .well-known folder. WebKeyDirectory.com
I’ve just published an updated blog post on BIMI adoption! Key highlights: 28% increase in overall BIMI records since May 2024. 64% surge in domains with BIMI configuration errors. Over 8% of VMC certificates are expired, and 10% are invalid.

We’ve enhanced our BIMI validator to include checks for Entrust certificates issued after November 15, 2024. These certificates are no longer trusted by Apple, meaning their recipients (@icloud.com, @mac.com, and @me.com) may stop seeing the verified logo. uriports.com/tools?method=bi…
Since December 11th, @comcast DMARC aggregate reports have shown irregularities. If you're a system administrator noticing a dip in reports, rest assured this is not an issue on your end. The problem lies with Comcast’s reporting system, which we hope is being addressed promptly.
Just got my first batch of @EverySmartHome EPL presence sensors! With the new zone configurator, they might just replace my Aqara FP2s. They’re noticeably smaller, and my first impression is very positive! First task: designing and 3D printing a corner mount.
If you're looking for an easy way to mount an Everything Presence Sensor in the corner of your room, my design is available for free @ Thingiverse: thingiverse.com/thing:687016…
Here’s my final design: The sensor eventually mounts high near the ceiling with white cable. Screwholes are included, but nano tape works too. Wire can run through the back or via the top center hole and then through the top of the Everything Presence Lite sensor.
Fellow email nerds, quick question for you—without peeking at the RFC! What types of reports does DMARC support? This question is taken from learndmarc.com/quiz. #DMARC #email #authentication #deliverability

We've made a small update to our learnDMARC.com project, now displaying the DKIM signature key size as well.
Nearly 10,000 of the top million domains have an MX record hostname containing one or more underscore characters. Is that allowed?
17%Yep, totally fine.
33%Nope, not allowed.
50%Not allowed, but works.
0%Who cares?

Kinderopvang KidsLodge verzorgt tijdens de avondvierdaagse de meeste straatvervuiling door reclamestickers uit te delen 🤦♂️. Gaan jullie de route straks ook opruimen @KidsLodgeHouten ?
