What does TRL mean to you in this context ?

I can't decide if you understand the impact of light pollution and don't believe it matters, or if you don't know the impact of light pollution and so don't understand why it matters.

If you understand the problem and don't believe it matters then I have nothing else to add. I respect your choice of belief.

Otherwise: light pollution disrupts wildlife, impacts human health, wastes money and energy, contributes to climate change, and blocks our view of the universe - this last one being something humanity has enjoyed for thousands of years.

It's possible these are not topics that concern you - that is entirely your option - but it does concern other humans who quite enjoy the night sky and would love to pass it onto the next generations better than it is now.

Sorry to hear that happened to you. They do lock out domains that were previously registered and still active from being re-registered [that's happened to me too]. Their Support should have offered you to contest and take over. It's not immediate [takes several days to go through the process and the departed employee will delay things] but if you can demonstrate positive DNS record control and go through the motions with support it does get done and you gain control. If they didn't offer it to you over support, try asking for it [if you are still wanting to go ahead with it]. It's not great speed but it also serves to protect you should someone else at the company decides to impersonate you and recreate the domain.

Best of luck!

DNS labels are limited to some ASCII characters. UTF support in DNS is available via punycode which is an encoding from UTF onto that restricted ASCII set acceptable for DNS. Libraries as the ones discussed here typically perform UTF to punycode conversions before doing any label comparisons to ensure accuracy. In particular this tolower implementation would likely be used against the punycode encoded version of the UTF domain.

Neither DKIM nor SPF provide domain owners with a verifiable disposition policy and monitoring. You should deploy SPF, DKIM and DMARC together. At that point either SPF or DKIM may pass but if the passing SPF/DKIM domain(s) don't match the DMARC domain the message isn't authenticated. Unlike SPF, DMARC will load its policy using the From: header, and thus ensure alignment between envelope-From and From: header (for SPF), or DKIM domain and From: header.
