Questions
What checks are there?
DNS lookup, domain registration details, MX, SPF, DKIM and DMARC checks with a fix list, an email header analyzer, reverse IP and IP owner lookup, an open port check, an email signature generator, a domain name generator, a PGP key generator, a contact card QR generator and a DMARC report analyzer.
Do I need an account?
No. Every tool works without signing in. Signing in raises the lookup limits and lets you keep a list of domains to watch for expiry.
What does it cost?
Nothing. The tools are free. Orbitly Mail and the rest of the suite are optional.
Are my pasted headers, keys and signatures private?
Yes. The header analyzer, signature generator, PGP key generator, contact card and DMARC report analyzer run entirely in your browser. Lookups send only the domain or address you typed.
Why is the port check limited?
To stop it being used for scanning. It checks one port on one public host at a time, refuses private addresses, and limits how often any host can be checked.
