DNS Mail Info vs DMARCFlow

This app is used to troubleshoot domain based email problems. It allows you to add any number of domains (limited by the hardware you are running it on) to test your DNS resolvers. Specifically, for BIMI, DMARC, NS, MX, SPF, and WhoIs records. The data is stored locally after a DNS refresh request has been performed. You can refresh one domain, or all of them at the same time. Once the domain data has been gathered, you can save a snapshot (or more). If a snapshot is different than the current information, the snapshot will highlight so you can review the changes. If you have a DMARC reporter configured, quick reports can also be made. Currently supported DMARC providers are Postmarkapp.com and Demarkreport.com. With access to other DMARC reporter's API, I can add others. Features: - Look up domain records using the default name servers, or from a list of public nameservers. - Domains can have a spefified default name server. - Domain look ups can be saved, and are tested for differences with last domain refresh - WhoIs information is also saved and is tested for differences domain refresh. - Many on-line DNS tools are simple click from within the app. - DNS records collected are: BIMI, DMARC, NS, MX, and SPF. - Whois record is collected - A set of example domains can be added as a quick start. - Mail can be sent to the domain MailTo using the host mail client - Refresh a single domain's DNS records or all of your configured domain's DNS records Roadmap: - Domain PDF reports can be email'ed or printed - Mail can be sent to a specific MX server.
