All DNS lookups run locally through PHP’s native `dns_get_record()` function. The MTA-STS checker also fetches the domain’s MTA-STS policy file over HTTPS (see External Services below). #### SPF Checker * Analyze SPF records for any domain * Monitor DNS lookup count (RFC 7208 limit of 10) * View SPF record structure in an interactive tree * Per-mechanism lookup count breakdown * Health status indicator (Good / At Limit / Critical) #### DMARC Checker * Analyze DMARC policies and configuration * Interactive DMARC record builder * Tag parsing with descriptions * DKIM and SPF alignment checks * Reporting configuration (rua/ruf) verification #### TLS-RPT Checker * Check SMTP TLS Reporting configuration * Validate mailto: and https: reporting endpoints * Health scoring for TLS-RPT setup #### BIMI Checker * Verify Brand Indicators for Message Identification setup * Visual logo preview * VMC (Verified Mark Certificate) detection * Custom selector support #### MTA-STS Checker * Verify MTA-STS DNS TXT record * Fetch and parse the MTA-STS policy file * Mode detection (enforce/testing/none) * MX host listing from policy * Max age analysis #### Common Features * Copy to clipboard for domains and record values * Fully responsive design (desktop and mobile) * URL deep linking — share results via `?domain=example.com` * Visual health indicators for all checkers * Powered by dmarcreport.com watermark ### Usage Use the `[dmarcreport_domain_auth_checker]` shortcode with the `type` attribute: * **SPF** (default): `[dmarcreport_domain_auth_checker]` or `[dmarcreport_domain_auth_checker type="spf"]` * **DMARC**: `[dmarcreport_domain_auth_checker type="dmarc"]` * **TLS-RPT**: `[dmarcreport_domain_auth_checker type="tlsrpt"]` * **BIMI**: `[dmarcreport_domain_auth_checker type="bimi"]` * **MTA-STS**: `[dmarcreport_domain_auth_checker type="mta-sts"]` All checkers support the `?domain=example.com` URL parameter for deep linking and auto-analysis. ### External services This plugin performs DNS lookups and, for the MTA-STS checker, an HTTPS request to the domain being analyzed. No data is sent to any third-party API or service operated by the plugin author. #### DNS lookups When a user submits a domain for analysis, the plugin uses PHP’s built-in `dns_get_record()` function to query DNS records directly from your WordPress server. The domain name entered by the user is sent as a standard DNS query. This happens each time a user clicks the analyze button for any checker (SPF, DMARC, TLS-RPT, BIMI, or MTA-STS). DNS lookups are handled by your server’s configured DNS resolver and are not routed through any external API. #### MTA-STS policy file fetch The MTA-STS checker fetches the domain’s MTA-STS policy file by making an HTTPS GET request to: https://mta-sts.{domain}/.well-known/mta-sts.txt This request is sent to the web server of the domain being analyzed (not to a third- party service). It is made each time a user analyzes a domain using the MTA-STS checker. Only the HTTP request itself is sent — no additional user data, cookies, or tracking information is included. Since this request goes directly to the analyzed domain’s own web server, there is no third-party service provider with separate terms of use or privacy policy. The connection uses HTTPS with SSL verification enabled. #### Outbound links The plugin includes links to [dmarcreport.com](https://dmarcreport.com) and [autospf.com](https://autospf.com)( services by the plugin author, DuoCircle). These appear as « Powered by » watermarks and pricing call-to-action buttons within the checker interface. They are standard hyperlinks that open in a new browser tab when clicked by the user — no data is sent to these sites automatically by the plugin. * [dmarcreport.com Terms and Conditions](https://dmarcreport.com/terms-and-conditions/) * [dmarcreport.com Privacy Policy](https://dmarcreport.com/privacy-policy/) * [autospf.com Terms and Conditions](https://autospf.com/terms-and-conditions/) * [autospf.com Privacy Policy](https://autospf.com/privacy-policy/) ## Captures d’écrans [⌊SPF Checker — record analysis with DNS lookup meter and tree view⌉⌊SPF Checker— record analysis with DNS lookup meter and tree view⌉[ SPF Checker — record analysis with DNS lookup meter and tree view ## Installation 1. Upload the `dmarcreport-domain-auth-checker` folder to `/wp-content/plugins/` 2. Activate the plugin through the **Plugins** menu in WordPress 3. Add the shortcode `[dmarcreport_domain_auth_checker]` to any page or post ## FAQ ### Does this plugin connect to any external service? The SPF, DMARC, TLS-RPT, and BIMI checkers perform DNS lookups only, using PHP’s native `dns_get_record()` function on your server. The MTA-STS checker additionally fetches the domain’s MTA-STS policy file from `https://mta-sts.{domain}/.well-known/ mta-sts.txt` over HTTPS. No data is sent to any third-party API or tracking service. ### Can I use multiple checkers on different pages? Yes. Each shortcode instance is independent. You can have an SPF checker on one page and a DMARC checker on another. ### What DNS records does each checker look up? * SPF: TXT record at `{domain}` * DMARC: TXT record at `_dmarc.{domain}` * TLS-RPT: TXT record at `_smtp._tls.{domain}` * BIMI: TXT record at `{selector}._bimi.{domain}` * MTA-STS: TXT record at `_mta-sts.{domain}` and policy file at `https://mta-sts.{ domain}/.well-known/mta-sts.txt` ### Is there a limit on how many domains can be checked? No built-in limit. Each check performs DNS lookups in real-time. ## Avis Il n’y a aucun avis pour cette extension. ## Contributeurs/contributrices & développeurs/développeuses « DMARCREPORT Domain Auth Checker » est un logiciel libre.
