A directory of domains we have looked up - mail servers (MX), SPF and DMARC. These are public DNS facts only; no email addresses or personal data are shown.
1,654 domains in the directory
Each entry links to a page with public mail-server facts for that domain: its MX records, whether it accepts mail, catch-all status, and SPF/DMARC policies. A domain appears here only after someone has checked it. No individual email address or mailbox is ever revealed.
Have a question, want your data removed, or want us to stop checking your mail server? Reach out - we respond to every message.
