MXBLACKLIST / INFORMATION
Mail Diagnostics with Clear Boundaries.
MXBLACKLIST reads DNS and existing blocklist data. It does not submit spam reports, upload messages, request new listings or send removal requests. Any review request is your own action on the provider’s website.
MXBLACKLIST helps people read mail-related DNS and blocklist evidence without presenting a single score as the whole answer.
What We Offer
Inspect incoming MX, published SPF and exact-name DMARC records. Check a public IPv4 sending address on SpamCop and inspect PTR records. Read timestamped results alongside guides explaining what was and was not tested.
Independent and Useful
This site is part of our independently operated internet-utility network. It is not affiliated with SpamCop, Spamhaus, Google, an email provider or a delisting service. No account, API key or ad click is required.
Help Improve Accuracy
Send a minimal reproducible example and the expected behavior, supported by an authoritative technical reference where possible. An incomplete lookup is treated as unknown, not as an unlisted result.
Questions, corrections, privacy requests or advertising enquiries: [email protected]. Do not send passwords, API keys, complete message bodies or confidential customer records.
