Show HN: DMARC.quest SPF/DKIM/DMARC Demystified

Hacker News - Fri, 07/31/2026 - 12:15am

You need this. You don't even need to sign in. Just go to the site and enter a domain name you have outbound email from.

When you setup DMARC you need an address to receive reports -- dmarc.quest can receive them, but unlike existing services, an AI agent monitors them ongoing, providing signal over noise.

Yes the UI is still a sloppified mess, but the quality of analysis of the agent is world class, this discovers configuration issues in setups all the time.

Show HN: An AI skill for filtering and reading Hacker Newsletter and others

Hacker News - Thu, 07/30/2026 - 11:33pm

An AI skill for filtering and reading newsletters, created especially for Hacker Newsletter (https://hackernewsletter.com/). Adjust your filtering rules letter by letter to teach it what interests you and what doesn’t. It includes Python code that shields all emails except those from selected senders. Of course, even though the LLM is forbidden from reading files containing keys or changing the code, it could still do so.
