Hi Product Hunt, I’m Joe, founder of Cybaa. Adding an email service, changing DNS or renewing a certificate can affect authentication and mail transport. I want Cybaa to help you check what happened and work out what to investigate next. Our August update adds DMARC and TLS-RPT reporting to the platform, alongside the domain and website security checks. For example, a sending service might pass SPF and DKIM for its own domains while failing DMARC because neither result aligns with the visible From domain. You can inspect that source, review the authentication and alignment evidence, then check later reports after changing the configuration. The update includes: * Email reports: daily trends, source investigation and SMTP TLS failure diagnostics. Sending IP blocklist results sit alongside the report evidence, with their own check times. * Free DNS tools: look up individual records or review domain infrastructure and published security policies, without signing up. * More web security checks: COOP and COEP checks in the free Security Headers checker and recurring Domain Monitoring. * MCP private beta: compatible AI agents can run Cybaa’s read-only checks using API keys. Email info@cybaa.io to request access. We’ve also improved notifications for DNS backup changes and published email-security records, and continued making the interface more consistent across our products. DMARC, TLS-RPT and reported sending IP checks are included in every plan. You can start a 30-day trial or try the public tools first. Add a reporting domain and follow the DNS instructions to begin collecting reports. When an email report shows a failure, what information do you need before you can decide on a fix? I’d like to hear where your investigation usually gets stuck.
