MXBLACKLIST / INFORMATION
Privacy & Data Handling.
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.
The service needs a public domain or sending IP to perform a check. It does not need your messages, mailbox password or contact list.
Diagnostic Inputs
The entered target is sent to our server as an API query parameter. Our server queries Google Public DNS over HTTPS; SpamCop DNS questions can also be processed by SpamCop’s DNS infrastructure through that resolver. Google requests use a zero-length EDNS client-subnet hint. We do not append the individual visitor IP to upstream DNS questions.
Connection and Operational Data
Cloudflare and our OVHcloud-hosted service process IP addresses and HTTP information to deliver and protect the site. The application uses source addresses for IP responses and temporary in-memory request and lookup accounting. API targets appear in request URLs, which infrastructure systems may process. We do not promise zero logs or retention periods for providers outside our control.
Reports and Browser State
The application does not save diagnostics in a database, cookies or local storage. Results remain in the page until changed or closed. Copy and download actions occur only when selected; saved files or clipboard contents remain under your device’s control. If you ask a connected browser agent to run a check, its result is also returned to that service under its own policies.
House Promotions
Current banners are self-hosted, without an advertising-network SDK or application click tracking. Following one opens SnapSub or Amazon, where the destination’s policies apply. Third-party advertising or tracking would require a new privacy and consent review before activation.
