  • This isn’t really going to be accurate all the time. It is a totally reasonable configuration to use a mailserver not in the MX records. Lots of companies that send automated emails use a service like mailgun or sendgrid as a relay, which isn’t their MX server. It doesn’t come from their company’s mailserver. The only way to validate that is by adding mailgun/sendgrid as an include in the SPF record.

    PTR records are very difficult to maintain for any accuracy since lots of companies use cloud providers and don’t bring their own IPs.

    You’ll often miss things like “Your credit card expired” or “please change your password” or even “Here’s your monthly bill from the power company” emails.



  • When you send an email to a mail server, you can set the “FROM” address to literally anything. The mail server does not care and forwards stuff on, as long as you’re authenticated. Anyone can run their own mail server anywhere that will dutifully just relay emails, which is what spammers often do. There are entries in DNS called SPF records (Sender Policy Framework) which mailservers use to validate on the receiving side that the FROM address coming from the mail server matches with a list of allowed mail servers IP address(es). If it doesn’t match it gets sent to spam, or outright rejected (depending on if the record says ~all or -all). It is often not ideal to reject any message that fails this check, because if you have some local system that runs its own mailserver and sends alert emails it might not necessarily match.

    I wear sunglasses to drive all the time. If I look down at the touchscreen to use the nav it beeps at me and tells me to keep my eyes on the road. It will even detect if you have a phone in your hand. Where do you see that it doesn’t monitor in any useful way? Would you prefer that people not be reminded of distracted driving?

    Im really curious as to how a nissan gathers details about sexual activity. I mean teslas have interior cameras that use image recognition to confirm that your eyes are on the road for safety, The data verifiably never leaves the car and is never saved but “Collecting data on facial expressions” seems like kind of a weird and dishonest spin on that.

    “Volkswagen’s cars reportedly know if you’re fastening your seatbelt” Is that just the occupancy sensor and seat belt sensor letting you know you forgot to fasten your seatbelt? or that one of your passengers is unbuckled? I wouldn’t consider that an invasion of privacy.

    Collecting the data is not whats important when theres safety implications. Its what’s done with the data thats important and potentially privacy invading. Nissan does have the term about selling your data in writing, thats probably more of a legal blanket statement to cover them in the future for some super weird edge case.

    Generally speaking privacy invasions are more aligned with free services
