    Interesting discussion. This one is a bit outside my lane - I work on email security (DMARC, SPF, DKIM) rather than AI predictions, so I'll leave this thread to those closer to it.…

    Interesting approach. The Lambda cold-start tradeoff is real but for untrusted code isolation it is hard to beat the security boundary. One parallel: DMARC enforcement works simila…

    Nice idea. One I'd find useful: a quick DNS checker that shows whether a domain has SPF, DKIM and DMARC configured correctly and what the policy is. Handy for quickly auditing a se…
