Privacy Policy

Information about how smtpprobe handles data when you use it to probe a mail server.

Legal entity details not yet available. Smtpprobe is in development and the business owner has not yet registered a legal entity or provided a registered address, jurisdiction, or contact email. This page will be updated with the operator's legal details when they are supplied. Until then, no data is collected, stored, or transmitted beyond what is described below.

What smtpprobe does

Smtpprobe is a diagnostic tool that opens an SMTP connection to a mail server you specify, reads its greeting banner, and reports the capabilities it advertises. The tool is designed to answer a single question: what does this mail server say when something connects to it?

Data sent during a probe

When you enter a hostname and click Probe, smtpprobe sends the following data:

  • Hostname/port — the mail server address and port you entered. This is used solely to establish the SMTP connection.
  • SMTP commands — a standard EHLO handshake (the same thing any mail client sends). No email messages, credentials, or personal data are transmitted.
  • IP address — your browser's IP address is seen by the probe backend during the request, as with any HTTP connection to a web service.

What is not collected or stored

Smtpprobe does not have accounts, sessions, or user profiles. It does not:

  • Store probe results or hostnames on any server
  • Log SMTP conversation contents
  • Use cookies, tracking scripts, or analytics
  • Send email or notifications
  • Share data with third parties

Probe results exist only in your browser during the current page session. Refreshing the page or navigating away clears them.

Connection behaviour

Each probe opens a single SMTP connection to the server you specify. The connection sends only an initial greeting and an EHLO command — authentication is never attempted, and no email data is transmitted. The connection is closed immediately after the server responds with its capabilities. The probe does not verify, validate, or act on the information it receives.

Changes to this policy

This policy may be updated as smtpprobe develops. The owner will update this page when legal entity details are available and when the service status changes from development/preview to general availability.
