Hi HN, This is a project [1] I've been working on for a little while and I'm interested in your feedback and point of view. Many of us would have verified a domain name by pasting a string into a DNS TXT record. Some providers ask us to store this DNS TXT record at a domain using a DNS label like "_provider" e.g. _provider.yourdomain.com, and some providers ask that you do it at the zone apex (God help us [2]). The Domain Verification protocol stores a DNS TXT record at a DNS name derived from a hashed "verifiable identifier" (think email, telephone, DID), enabling anyone that can prove…

Hi HN – Kristyna here. I built this free, online email validator and would love to share it with you. What it checks: - Syntax – Confirms correct proper email format. - Domain & DNS – Verifies the domain exists and resolves. - MX records – Verifies the domain can receive mail. - SMTP handshake (optional) – Checks the mail server accepts the recipient (no message is sent). - Disposable domains – Flags temporary inbox providers that can hurt deliverability lists. - Common typos – Catches mistakes and suggests fixes.

I've been researching the bot & proxies space for years. I slowly incubated a service to protect public forms, contents and APIs. It recenty reached a few million daily requests and I now dare to bring it to light. Truesign detects bots, proxies/vpns and fake emails, through a single request from the browser, without challenges or user interaction. It can block the request based on rules you choose, or grant a token with encrypted information about the visitor for you to decide. I created a few pages to showcase how it works: - https:/demo.truesign.ai/protected-form : a form…
