Kids nowadays will never understand how cool it was to have a Sound Blaster, an Athlon Thunderbird and Voodoo graphics. I might be nostalgic, but to me it sounds much cooler than having a 11700k with a 4090 nowadays

I've worked on something similar while in college. HDMI is actually a fairly simple protocol, based on VGA. It still has scanlines and such, but the signals are digital instead of analog. So instead of a RAMDAC, you have the HDMI encod

In most countries there is a mandatory periodic technical examination for motor vehicles (like MOT, TÜV, etc) where lights are tested for exactly this reason. Also, I don't think people tilt their headlamps up on purpose.

This is typically not a big deal, as explained in the message, it is a temporary countermeasure. It'll resolve itself as long as you really aren't spamming. Though Gmail responds citing your IP, Gmail and all other large email s

It's because anyone can send email from any email address. SPF, DKIM and DMARC prevent impersonation on the domain level, but not the account level. Basically, if you can send using you@domain.com, you can also send as someone_else@dom

Neither Google or Microsoft use long term IP reputation. They may temporarily block an IP for various reasons (it will even reflect that in the SMTP error message), but never in the long term. All major email service providers work with dom

rcme is right though, DANE and MTA-STS are still opportunistic, the sending party must support DANE/MTA-STS to use it. And even still, with both DANE and MTA-STS, you are merely "asking nicely" to use TLS, the sender may stil

> Even SPF isn't enough anymore. SPF is a old and horribly broken standard, and should not be relied on for at least 10 years now. DKIM and DMARC is the way to go for outbound SMTP. Google didn't break SMTP, spammers did.

Be careful with doing this, be sure you understand the implications of simply copy/pasting such an SPF record. For most situations, your MX (which is inbound email) may not necessarily be sending (outbound) email. For example: when usi

There is no randomness, this is how DMARC works. You need SPF or DKIM alignment (either one will do). Basically what is happening, is that Gmail is slowly enforcing DMARC for new domains. This is a good thing, any domain that sends email

DMARC is an anti-impersonation standard, not anti-spam. DMARC alignment is trivial to set up, so even spammers can do that. That, amongst other reasons, is why all major spam filters are based on content, not DMARC alignment. This is why yo

This is exactly what SPF and DKIM are designed to do. DMARC enforces this. Obviously, this is opportunistic security, the receiver must support all this, but >99% does.
